I've also had this problem with my Dell laptop. But somehow it ended up
fixing itself. Now I'm having a similar problem on my desktop

your issue here. It could also be a video card problem, as in the case
with some ATI cards, theres a small vista workaround posted on the help
pages at AMD. I'll post it here for you incase its related:
