XP explorer problems...

Hi guys,
I'm having some problems with IE runing under XP.
The font that the computer now uses when displaying web pages is HUGE!. I had a similar problem a while ago, but that time the font was so small I couldn't read anything. That time I fixed it by re-formatting and reinstalling XP. I loath to do that again.
I've searched the web and MS's KB site, but I can't find anything relevant.
I've not changed any settings, or removed or added any fonts, it seem to have happened all by itself.
Any ideas how to fix this?
EDIT: I've just noticed that this problem only occurs on my user account.
