Today I've faced with a problem – Opera 11 couldn't start on Windows XP and showed the following error:
Opera has failed to access or upgrade your profile. This may have occurred because your computer has insufficient recources available or because some files are locked by other applications.
The following works also in other applications (not only in Skype) that use a web-cam and don't work with your video-camera connected to your PC through FireWire (for example).
By default Silverstripe CMS doesn't have any means to place a custom javascript snippet at the very end of the head section just before "</head>" closing tag. I faced with this today because I wanted to put Google Analytics tracker code there. Of course, I know that technically one can place this code anywhere, but I had problems with my statistics and I wanted to be sure that I did everything as Google said.
