There's a box on the top left corner of the desktop. Usually it's about half its size only in height. The length is same. I can't right click or anything, if I try to jump into properties on my desktop by clicking on that empty spot it does nothing.
It doesn't show up on reboot only after awhile does it magically appears, but not sure when. I think it showed up recently, and usually the My Computer icon is on top of it. If an icon is on that spot, I can't click on the icon either.
Anyone know how to get rid of it? I don't think its a virus either, my AVG haven't picked anything up, nor did my Spybot.
Running Vista Ultimate x64 btw. Thanks in advance.
Here's a screenshot on the attachment.
