All browsers displaying italic text when not supposed to

Question

I am having a problem with my browsers (Safari, Chrome, and FF) displaying text in italics when it's not supposed to be italicized. This is happening on multiple sites including Google sites (Google, YouTube) as well as sites I have built and others (godaddy email, ford.com, even stackoverflow). Surprisingly though, it is not happening with my time tracker site (freeagent.com).

I have no idea what's going on. I have not installed any new software recently nor any new fonts. I am running Mac OS X lion.

Answer 1

I had the same problem where all the email titles were bold in my GoDaddy Email, on several browsers and only at one computer. It all happened after installing Suitcase Fusion and copying over a font library to that specific computer. I followed Lisa's suggestion and permanently turned on another version of Arial (TrueType, version 3.05) and it did the trick: all the email titles are back to normal (bold if unread, regular if read).

Answer 2

I've been having this problem... text bold and italic in all browsers, websites, twitter, even emails... what I did to fix it was make sure that Arial was turned on permanently in my Suitcase... it should have been anyway as a system font I guess but who cares because it fixed it!
