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.
