Corrupt fonts?!


Hi There

I installed about 200 fonts onto my G5 iMac (running Tiger) and now I've got a really odd font issue that is driving me crazy. Basically some emails in Mail and some system alerts / text in different software programmes has defaulted to a hideous-looking graffiti-style font instead of the correct system font. I've tried tracking this font down in Font Book, but I can't seem to locate the font itself on the system (Library?!). Furthermore, Microsoft Word takes a good 30-40 seconds to load and the drop-down font menu has become illegible, with the letters making up the name of each font squashed together over the top of each other.

Short of a clean install of OSX, is there an easy way out of this? I thought about getting hold of a list of all the standard fronts in OSX, MS Office, Adobe CS etc then deleting the ones not on the list, but I don't want to spend the rest of my life doing it!

Thank you in advance!
