Thank you both. I'm about to the place where we're probably just going to back up any data files of value, clean off the drive and reinstall XP from scratch. It would be good to do this because there's a lot of extra stuff on the drive that has accumulated over the years that doesn't really need to be on there any more. Thanks again for the suggestions.

If future generations are to remember us with gratitude rather than contempt, we must leave them more than the miracle of technology. We must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.
