I was losing the mouse and keyboard on my PC, and did a re-installation of XP to (I hoped) replace any corrupted files. I don’t know if it worked yet, but whatever.
After the installation, I attempted to play a youtube video. It failed to play; I was getting a messed-up progress bar along the bottom, with the buttons missing. Tried a couple of other videos; same problem. Went to a Yahoo video; same problem, with slightly different symptoms. The Yahoo site got stuck on an animation while saying it was loading the video. If I believe this, it looks like the problem may with loading the video, rather than playing it. Seems a little odd, but okay.
I decided I was screwed, but that maybe upgrading from ie6 to ie7 would help. Not surprisingly, it didn’t.
Any ideas, apart from getting a different browser?
