When I have Classic program files open that have changes that need to be saved, when I go to the menu bar and stop Classic, it stops without asking to save the changes. The screen goes black in places for a split second as Classic is quitting. I've seen it ask to save changes on other computers, but I can't get it to ask on mine...a PowerBook G4 1 Ghz or a G4 AGP Tower. I've tried various versions of OS X from 10.2 to 10.4.
