So I figured, no problem, I'll just restart...it still happens. This was like 5 or 6 days ago.
Here is an image of it.
It wouldn't be such a problem (I can still close it using ALT+F4) except that I like to use the Processes tab a lot, and now it's stuck on whatever tab it defaults to (Tasks, I think it's called).
Anybody know what's goin on?
