Why are some thing italiziced?

[m13120]

On my computer, I just restarted it, and without making any notable changes, when my computer restarted, I loaded up AIM and some of the things were italiziced. I'm not going to show my buddy list for obvious reasons.

Also when I went to google to do a search I noticed some things were also italiziced.

Does anyone know how I can reverse this to normal/nonitaliziced?

Nevermind I figured it out, just incase this ever happens to someone else, the only things that were being italiziced were Arial, and that's because somehow one of my Arial fonts were deleted so I just copied and pasted the one I was missing from my laptop into my Fonts folder and it worked.
