And you can try throwing out your Twin Turbo prefs. The System can't quit because the System isn't a program, so it has to be an application when it crashes, but it might be executing system code when it crashes. At that point, it doesn't know how to tell you what's wrong. Suitcase will do it. In fact, I think all the font management utilities can check for corrupted fonts.

A couple of months ago, a friend of mine went to Fry's in Burbank and had them upgrade her hard drive and her memory. It just occured to us recently, however, that they didn't return her old hard drive and the memory they had to take out to make room for the new memory. We called and asked them about it, and they said we keep stuff like that in a locker for about three months and then get rid of it. They're still looking for her stuff. No, always get your discarded parts when your machine is serviced.
