Powerpoint problem specific to user profile

Maybe you guys can help…
I have a user at a site who’s having an odd Powerpoint issue. It’s PP 2007 and he found that his margins and bullets on all the presentations he’s created in the last three weeks are screwed up. So he’s having formatting issues.

What’s very odd is that I can login to his machine as admin, browse to his directory, open up his Powerpoint presentations and all the formatting is correct.

I’ve tried uninstalling/reinstalling Powerpoint, ran a registry cleaner, and renamed his profile so when he logged in, he had a new, clean profile but he still has this weird formatting issues.

Has anyone run across this?

Thanks!
