No, they're still there. I was thinking it was a Virus but it could quite possibly be something in the settings. My first reaction was to go into the registry and change NoDisplayBackground and NoDisplayScreensaver back to 0 but they were both already like that. ><

To elaborate more. There's about a centimeter cut off on the top of the screen that has no been replaced by a black bar. The toolbar no longer stacks windows properly and starts stacking them vertically when it runs out of room instead of making them smaller where it is very hard to get to.
