Ok, I hated the normal alt-tab interface of windows 7 so i decided to install vista-switcher. It worked great until a few days ago. I see images of empty events that aren't there. I'm afraid they might be some kind of viruses of something. I've attached a screenshot, would be great if you guys could help me out on removing the virus if that is what it is, or get rid of those events if they arent.
PS. I did update the graphics driver
and even installed Intnernet Explorer 9 Beta recently, but these events seem to be there even before i run Internet Explorer.
