OK, after fixing permissions, restarting, installing then running the update, restarting, fixing permissions again...

My Apple applications (Mail, Disk Utility, Address Book, iCal and more) do not work at all, they won't even start up... when you try, the icon bounces in the doc for about 2 seconds then NOTHING...

I don't know WTF happened with this update, but something's not right. This happened once before with a Panther update and removing New Times Roman font fixed the issue... since it's not installed on my system, that can't possibly be the issue here.

Anybody have the same problems? Any suggestions? Ideas?
