I have had similar problems with my Powershot G2, when I used W2K. They mysteriously disappeared after reinstalling the drivers a couple of times.
After I installed WXP, I don't use the bundled software at all, since XP can access the CF card in the camera as a drive. I havent had any problems under WXP.
Have you checked Canons homepage for the latest XP drivers?
