Aw, thanks guys. It doesn't matter anyway. The problem is with my monitor. It only shows the bottom half of the screen, and the top half is folded over on itself. Is that bizarre or what?
I know it's odd that I thought my monitor problem was a software problem, but I've been having this problem on and off for a year or so. Everytime it happens I uninstall a bunch of uneccessary programs (kids games, etc), and it seems work again. So, since it happened this time right after a bunch of updates, I thought that was the reason. This time I could not get it to come back up. Since it still does it even in safe mode, it must be totally a monitor problem.
Off to look for a bargain. It's not really fun to have to shrink everything down to the bottom of your screen to even halfway see what you are doing...
