I should have replied with my solution earlier...
Something with the video refresh rate was screwed up, and it doesn't make a damn lick of sense, but I just changed the resolution from 1600x1200 to 1024x768, then back. This solved my problem. I also am not using a certified video card, but this is the first time in over two years that I've had this problem show up.
Anyhoo, chalk this one up to the WTF solution column.
Do they speak English in What?
