if you go to
www.insomniax.net, there is a forum and thread that explains how to go back to the WoW default font. It's actually pretty easy, from what little I gathered (I like the new font, so I'm willing to stick with it). Try this link:

I hope this helps you. I've been using IX for only about a month, and don't know how I leveled to 60 without it! It's one of the best compilations out there. I am eagerly anticipating the newest patch that runs better with WoW's 1.5 patch.
