Bold text and not so bold text

Hey, Jon, I had a quick question for you. Whenever I log on to the forum at work or at home, the text is all bold, even the normal text. Basically, I can only tell if text is underlnied or italicized. However, I just logged on with another computer, and the text is normal, and bold text looks definitely bold, whereas the rest does not.

Is it my IE that's outta whack? Or something else? They're running IE 5.00.3700.100 here, and I think I got IE 6 (or whatever the latest version is) at home & work.

Thanks!
