Rather than trying to use more than one monitor, creating a virtual desktop using Dexpot 1.5.10 might prove far more manageable. Simply create another desktop, create a keyboard shortcut and switch between the two (or three, four..). These virtual desktops enable you to run a browser full screen, perhaps use another for a video editor.

Why hasn't Wuala taken off as effectively as Dropbox? It's confusing, particularly when it's backed by a brand such as Lacie. This week a major new update was made available, Wuala "Hottingen" build 357. Wuala is a cross-platform cloud-based backup, file synchronization and sharing tool with a free 2GB account, in the same manner as Dropbox. With the new Hottingen release, users of the free 2GB account have full access to all features. Choose files from your backup cloud to share with colleagues, access old files through versioning and synchronize between your computers, whether they are a Mac or PC. You can access your files from a mobile device, such as Wuala for Android 1.18.12. What's not to like? We'd like to know.

Popular in the APAC region, Trend Micro Titanium Maximum Security 2012 beta was released this week, following BitDefender Total Security 2012 Beta which was released the previous week.

Only a few years ago, playing video on your PC was a real pain in the backside. There were so many codecs available that you had to have multiple video players installed just to show your video collection. However, that was the simple part. The hard part was trying to figure the codec used to encode the video you wanted to play in the first place. To achieve this, we used a video inspector that would indicate the video and audio codecs used to compress the video. KC Softwares VideoInspector 2.2.8 is a similar tool, from the developer's that brought you SUMo 2.13.4.111, which will also allow you to display the video resolution, bit rate and more info.
