Vista cannot see network shares

Computer Aid Posted on 29 October, 2009 by Luigi Martin29 October, 2009

After a few problems getting vista to see shared network drives on some network attached devices (and sometime on XP shared drives as well), I finally found the solution:

Start -> secpol.msc (in the Search field).

In the left pane: Local Policies -> Security Options. In the right pane: double click on: “Network security: LAN Manager authentication level”.

Local Security Setting tab -> “Send LM & NTLM – use NTLMv2 session security if negotiated” option. -> OK.

Seems like microsoft have used Vista to cut ties with the past (insecure) versions of network share authentication. Of course they failed to realise that network attached drives cannot be easily updated.

Firefox: a (not so) quick evaluation

Computer Aid Posted on 26 October, 2009 by Luigi Martin26 October, 2009

This is another of my browser quick evaluations.

This time, I’m evaluating Firefox, to see if its a suitable candidate in my quest to replace Maxthon as my default browser.

I’ve been using Firefox while working with Entrecard blogs, so I know it lacks multi-threaded tabs… its annoying, but not a huge problem.

The border width is the standard windows width… good.

firefox

Now for customisability:

At first, there doesn’t seem to be the ability to create your own toolbar, but I eventually find it: view -> toolbars -> customise -> add new toolbar.

OK, I’ll start by installing a pagerank add-on…  I install SearchStatus, and it can be placed on any toolbar/menu bar available to firefox… its an excellent addon.

Now onto advert blocking: I installed adblock plus, and flashblock, and using the standard settings, I hardly saw and adverts and all flash content was blocked until I pressed the “play” button. This is the best ad blocking I’ve seen so far, with hardly any training required from the start, and a simple ABP “button” to switch ads on and off.

RSS feeds worked, but the built-in feed reader (looks like an extension to bookmarks) doesn’t allow you to “mark bookmarks as read”… so I can’t be sure what I’ve already seen and what I haven’t. Looks like I’ll need to use an “external” feed reader (I’d rather use the reader built in to the browser).

Unfortunately, typing a URL into the address bar, and pressing enter caused the website to be loaded into the current tab… Alt Enter will open it in a new tab, but will activate the new tab… I tried the tabnavigator addon, but it didn’t do anything that I wanted. Next, I tried the “tab kit” addon. It worked, and it has some nice features (tabs on multiple lines, typing a URL in the address bar opens it in a new tab, grouping tabs, etc)

I wanted to switch between tabs by using ctrl-right arrow & ctrl left arrow. I tried tabnavigator, tab kit, and keyconfig (to remap the keys), but none worked. Its disappointing, but not a major problem

I wanted to close tabs by double-clicking on the tabs, and found a plugin to do just that (close tab by double click).

I also added an “undo closed tabs button” … nice.

drag and drop urls from a web page only works if you drag the url all the way to the address bar… I’d like to just drag it slightly, and it looked like it couldn’t be done, until I accidentally found what I was after (QuickDrag).

spellcheck: like opera, FF will check spelling in input boxes… but it only started working once I installed a dictionary (Australian).

I also installed the SearchStatus add-on… it displays pagerank (plus a few other ranking figures) on the toolbar… great for SEO work.

I installed firebug (web developer tools)… its nice, but I’ve found that Operas “developer tools” (dragonfly) is just so smooth and seamless. Dragonfly is so good, that I’ll happily switch browsers every time I need to do some website development/alterations.

Other add-ons I added are: “Menu Editor”.. when right-clicking on a link, I have now moved the option to “open link in a new tab” to be the first option in the context menu…. Remove New Tab Button” removes the unneeded “+” button at the end of the bar of tabs.

Exporting favourites from Maxthon & importing them (into Opera & Firefox) is a simple process.

So far, the biggest advantage of Firefox, has been the wide range of plugins… but that’s also its biggest problem, as its difficult to know what FF can do unless you’ve heard about a feature before.

Finding the quickdrag add-on is a good example of this… I knew what I wanted, but it took a day of idle searching before I found what I wanted.

I’ve heard that Firefox still has problems with memory leaks and memory bloat, but I didn’t really look carefully enough to make a conclusion.

But I can say that Firefox 3.5.3 has crashed, locked up, frozen, or just simply disappeared (gone from task manager as well) more times than all the other tested browsers, combined.

So, the final verdict: (Many people will say “I told you so”) I’ll be switching to Firefox as my main browser(with Opera as a website development aid). Its not perfect, but its my best option.

Unusual internet dropouts

Computer Aid Posted on 24 October, 2009 by Luigi Martin24 October, 2009

I recently visited an “Outside School Hours Care” centre (ie a centre that looks after school kids, outside school hours… usually before school, or after school… it helps parents handle unusual work hours).

They have 2 networked computers, which were behaving strangely… after a few questions, I got some unusual answers:

  • sometimes PC1 would be unable to get to the internet.
  • sometimes PC2 would be unable to get to the internet.
  • sometimes both PCs wouldn’t get to the internet.
  • and other times, their admin software (while reading data from the other PC over the network), would give network errors.
  • The schools (unfriendly) IT tech, said the ethernet port had failed, and installed a PCI ethernet card to get them going.

At first I though it might be a virus infection… but then I noticed they had a wireless modem router… When I ask about it, I’m told it was installed a few months ago (the previous modem had broken down)… but they didn’t know if the WiFi was active (they had no WiFi devices).

I’m then told their internet usage had skyrocketed over the last two months… and they have a caravan park next door… could that be the problem?

I think so.

The wireless was unsecured, so it wouldn’t have taken long for the word to spread amongst the caravan park…

I also mention that with the kind of file sharing they are using, they could find deleted files, corruption, etc.

It turns out they have had some unusual “missing documents” from the computers.

So I quickly enable WPA security, and do a spyware/virus scan.

The scan finds no infections. At least thats a relief.

With no more electronic “intruders” to worry about, everything seems to work smoothly. I even have some spare time to do some quick tuning and a defrag of the computers (with a big improvement in speed).

email: how to set the default browser

Computer Aid Posted on 22 October, 2009 by Luigi Martin22 October, 2009

I just had a situation, where I had changed my default browser (from Maxthon to Opera), and then found clicking on web links within an email would result in Maxthon displaying the web page.

I tried a PC restart, changing file type associations… but nothing would work.

I eventually found an interesting utility called DefaultBrowser, which fixed the problem quickly and easily.

I can’t be sure if its a problem with Opera, Thunderbird (email), or Maxthon… but it seems that changing your default browser isn’t as simple as it should be.

Microsoft Outlook: The address list cannot be displayed

Computer Aid Posted on 20 October, 2009 by Luigi Martin20 October, 2009

After transferring outlook to a new PC (and transferring emails / contact list), a customer got a strange error when composing a new email:

She would click on the “To:” button, but instead of getting a popup contact list, she would get the error message: The address list could not be displayed. The Contacts folder associated with this address list could not be opened…

But by clicking “OK”, she would be able to select a “second” contact list from a drop-down menu in the “select names” window… Its somewhat confusing , as both contact lists are called “Contacts”… But the second one does work…

I find Microsoft have a solution to this “contact list” corruption… remove and recreate the contact list.

Ah, Microsoft… as subtle as a sledgehammer.

I found a better solution:

  • From the main outlook window: tools -> address book
  • From the Address book window: tools -> options
  • Select the “other” contact list in the first 2 drop down lists, and change the order of Contacts in the “check names” list.
  • OK out of the window, restart outlook, and now the customer doesn’t get prompted about non-existent address list.

Opera Browser V10.0: a (not so) quick evaluation

Computer Aid Posted on 18 October, 2009 by Luigi Martin18 October, 2009

This started as a quick evaluation of the Opera browser, to see if its a suitable candidate in my quest to replace Maxthon as my default browser… but it ended up being a lot longer, given that Opera is a lot more capable than I originally thought.

I’ve used it on the Nintendo Wii, my windows mobile “smart phone”, and on my XP PC. In each case, it seems Opera had customised the browser to suit its environment (which must have involved a huge amount of effort from the developers).

It passes my first test: the window border is the standard windows border width, which changes whenever the appropriate setting is changed in display properties.

The second test is its ability to be customised to suit my browsing style. Yep, I can add a pagerank “widget”… but its awkward to use… Maxthon had a plugin that automatically displayed pagerank and alexa rank whenever you visited a website…

Opera has a great and easy way of blocking adverts… just right-click somewhere on the page, select “block content”, then click on the ads you want to block… easy. I also added Flash Blocker, so I could also block any flash code, unless I specifically click on the flash logo to run it.

RSS feeds: it works (barely), but after installing the latest version of Opera (10.0), feeds work in a much easier way (there’s a feeds menu!)

If I type a URL in the address bar, I usually want it to open in a new tab (if I didn’t want the current tab, I would have closed it)… Instead, most browsers (Opera included) assume I want to move away from the currently active tab… wrong assumption, and I find it annoying. But I can get around it by entering the URL and then pressing  ctrl-shift-Enter (instead of just the enter key)… unfortunately, the Enter key alone, cannot be “reprogrammed” to open a URL in a new tab 🙁

I soon discover that Opera can customise keys and mouse actions (tools -> preferences -> shortcuts)… But as you will see below, most actions I want to perform, cannot be done (or are not documented). The one nice thing I could program, was Ctrl right arrow, and ctrl left arrow to navigate the tabs.

I like to be able to double click to close a tab… But Opera cannot be configured to do this. The closest is to use ctrl-W … but that closes the currently active tab… not one I choose arbitrarily. And I hate closing tabs by playing “hit the target” with those small x’s. Note: after some more searching, I found that I can shift-click to close a tab… good enough for me.

I often find multiple links on a page, and I’d like to open them (each in a different tab), and then read through the content of each tabs I had opened:

This means when I right-click, then select “open in a new tab”, then I don’t want that new tab to “activate”, so that I can go and right-click on a few more links… but Opera (and many other browsers) like to make the new tab active… so then I need to go back to the previous tab, and then click on other links… time consuming, and I don’t like it.

But there is a workaround: Ctrl-Shift (left)Click will open a hyperlink without activating it, but again, this cannot be made the default behaviour for “open in a new tab” 🙁

Another nice feature of Opera 10.0: the undo button (its called “closed tabs”). This lets you re-open tabs that you might have (accidentally) closed recently. It would be nice if the history of closed tabs could survive a browser restart (the way Linux shell history does), but few applications seem to consider the simple task of maintaining a persistent “history” nowadays. Its often a case of “once the application shuts down, then erase all history”.

I like the built-in developer tools. For me, its very very useful in website development.

While editing this article, I noticed that Opera automatically detects text input boxes, then spellchecks words in the box, and underlines misspelt words. Right click on a misspelt word to correct it (or even to change the dictionary… its the UK dictionary for me!).

A minor omission is: no option to set Opera as the default browser… there is only an option to “check if opera is the default browser on startup”… which sometimes wouldn’t work… depending on what kind of startup options were selected (in my case: “continue saved sessions”).

A disappointment, is not being able to drag  a highlighted url/link from a web page, and drop it into the tab bar, to open the link in a new tab. Maxthon has this feature really well organised (where you can just drag and drop it on the same page, and it still opens the URL in a different tab… very convenient!).

Another problem I’ve encountered (but it might be a google problem, rather than an Opera problem), is that I cannot login to gmail… but I can sidestep the problem by logging into google contacts, and then using the link at the top, to get to gmail.

After using Opera for about a week, I started noticing more websites that would not work. Most notable was Google Adwords… that website actually says: “We’re sorry, the new AdWords interface does not work with Opera”

I’d like to be able to create my own “favourites” toolbar, and place it next to the menu bar (to the right of the “help” menu), but but again, Opera is not that customisable. At least I can use the “personal bar” toolbar for my favourites/bookmarks, but not for widgets… Grrr.

Something in Operas favor, is its memory usage. It seems to have no memory “leaks”, and with 100 websites open, it doesn’t crash, and doesn’t seem to slow the computer much (obviously the slowdown you get depends on how much RAM you have… but Opera seems to use it more efficiently).

operaMaybe I’m expecting too much? Maybe I’m part of  a minority of browser users who value function (and customisability) over form (like pretty buttons, colours, and “sexy” effects) ?

In summary: Opera has almost all the functionality I would want from a browser. Its the best browser I’ve evaluated so far… similar to Maxthon. The biggest disappointments were:

  • A very limited number of widgets and plugins which might have allowed me to overcome the annoyances I encountered.
  • Websites that just refuse to work with Opera (and I wasn’t interested making Opera “impersonate” another browser would solve the issue.

Next, I’ll take a look at firefox… does it deserve its huge popularity? Stay tuned…

outlook 2003 cannot add pictures to signature

Computer Aid Posted on 16 October, 2009 by Luigi Martin16 October, 2009

I installed outlook 2003 (on a new PC) for a customer, and copied all her data from the old PC.

She calls a few days later, saying she can’t add any pictures to her signature.

I figure it must be something simple. I take a look, and sure enough, the signature has text (even different fonts, with different colours), but I can’t add a picture.

When I click on the “edit signature” button (tools -> options -> mail format -> signatures -> edit -> advanced edit -> yes), I get the signature opening as html in notepad…

So the first thing I try is adding a html IMG tag to the signature, with reference to a local image… but then the signature shows a blank square, with a red “X”… somethings not right… particularly since the old PC was displaying signatures with images in them…

After an unusually long search, I eventually found the simple solution:

tools -> options -> mail format -> compose in this message format -> Rich text (don’t select html)

Now when you edit a signature (advanced edit), outlook will open word (instead of notepad), and will allow you to insert an image directly into the signature,

Google Chrome: a quick evaluation

Computer Aid Posted on 14 October, 2009 by Luigi Martin14 October, 2009

This is another of my browser quick evaluations.

This time, I’m evaluating Google Chrome, to see if its a suitable candidate in my quest to replace Maxthon as my default browser.

Since Chrome and Safari are closely related, I suspect that Chrome will end up like Safari, and will be dropped from my list.

First up: border width. I must say that the border width is thicker than Safari. But a quick change in screen resolution reveals the truth… Chrome does have a thicker border than Safari, but like its cousin, its a fixed width that is independent of the thickness set in the windows display preferences. For me, that’s a no-no.

chromeI can see that it also lacks any way of customising the look and locations of “toolbars”… in fact I cant see any way of customising Chrome.

Again, I just can’t see myself (as a browser power user) using Chrome for any length of time.

abbyy fine reader… missing words

Computer Aid Posted on 12 October, 2009 by Luigi Martin12 October, 2009

For the first time in over 4 years, I had a customer that actually needed to use OCR to convert some scanned images into text (to be inserted into a different document)… but without needing to re-type the scanned images for many hours.

The first thing I looked for was a scanner.

I knew that if the customer had a scanner, then the scanner software invariably contains an OCR package.

She had a Dell multi-function printer/scanner… good.

since the scanned images were embedded into some PDF documents, I first had to copy/paste the images from the pdf document into an image viewer (like IrfanView), so that I could save a JPEG file… I could then get the OCR software to “interpret” the image.

It turns out the OCR software was Abbyy fine reader.

And it seemed to do a great job except for one vital flaw: many words would skipped.

It didn’t take long to see what was happening: only basic words like “the” and “had” and “from” were being interpreted… and other, more complex words, were being deliberately blanked out.

I just didn’t have time to look into Abbyy more closely, but I suspect that it was just a “demo” product, as the help had some mention of purchasing the professional version…

Since the customer didn’t want to learn how to save images from a pdf document, and then learn for to use Abbyy, she decided to find another workaround.

But I found 2 annoying aspects to all this:

  • Abbyy will not interpret “scanned images” embedded within PDF documents.
  • Why bother including hobbled software (like Abbyy) with a scanner… it might result in an extra sale, but its twice as likely to result in an unhappy customer…

internet explorer won’t display certain images

Computer Aid Posted on 10 October, 2009 by Luigi Martin10 October, 2009

This is something that I came across over 1 year ago, but it happened again recently, in a slightly different context, so I thought I’d cover the topic again.

Many people don’t realise this, but there are 2 types of jpg images:

RGB (its what most people use)

and CMYK (used by graphic design companies)…

Often, you cannot tell the difference, unless you use an image viewer like IrfanView… where, if you view the image properties, you will see the compression field will be either “jpeg” or “jpeg, cmyk”

The big problem, is that Internet Explorer and Chrome cannot display CMYK images, while Firefox, Opera, and Safari might be slow to display them.

Note: soon after publishing this post, I noticed that Chrome could actually display CMYK images… probably due to an update.

Here is an example:

Logo in RGB:

ca13-twitter-100x50

Logo in CMYK:

ca13-twitter-100x50-cmyk

Obviously, you can only see the CMYK logo if you are using Firefox, Opera, Chrome, or Safari

MYOB Premier is slow over a network

Computer Aid Posted on 8 October, 2009 by Luigi Martin8 October, 2009

Now this was difficult to solve.

Customers’ accountant had upgraded to MYOB Premier, so that it should run over the network, and be accessed by 2 or 3 different PCs (Although it was still going to be used mainly from just 1 PC).

I get called a few weeks later, and get asked to look into the “server” because MYOB is running slow, and sometimes just wouldn’t even open the database file.

Apparently, the accountant had said she had setup MYOB Premier in many different environments, and she had never encountered any speed problems… in hindsight, I shouldn’t have trusted this nugget of useless information.

Since the server was just a windows XP home PC (but a reasonably quick Acer 3.2Ghz P4 system), I ended up doing a lot of stuffing around creating a “proper” server, only to find that the new environment had created other difficult issues (see my previous post on using linux as a file and print server).

In the end, I found a few things that resulted in a solution:

  • When MYOB starts, I changed the default protocol from NetBeui to TCP/IP (some say NetBeui is faster, but at that stage, I was willing to try anything).
  • Both the server and the main MYOB PC had Gigabit network cards, but the router ran at 100Mbit… I installed an Asus Gigabit switch between the server and the wired PC, so they would run at full Gigabit speeds.

After that, MYOB seemed to run “reasonably”, and with none of the original problems.

After some further research, I found that MYOB (probably because its not efficient at working over a network) can shuffle huge amounts of data across the network… so running Gigabit would have helped a lot.

I suspect that the amount of data transferred might be related to the size of the company database… and in this case, the company file was reasonably large (about 30 Mb).

A difficult problem to solve, and for the first time: a customer that wasn’t happy about the “size” of my invoice… But that’s another story.
