If you are in OSX and go into Preferences --> Classic --> Advanced --> Rebuild Desktop you can rebuild the classic desktop while in OSX. I have found this usually clears weird Classic Bugs.
I have also found that booting into OS9 and running Diskwarrior or Norton's causes havoc with OSX because they don't recognise OSX files and consider them corrupt. However, if you are not using OSX, and are just using 9, DIskwarrior is the best solution IMHO. Regards, Nathalie
