I also have the finder quitting upon start up, tried trashing the finder prefs & rebuilding desktop, but neither one worked. I tried to zap the pram, using the "cmd+option+p+r" keys after shutting down, but when i do this, all the machine does is sound as if it is starting up, then quits, then sounds like it will start up again, then quits. my screen goes to blank grey at first then goes black, then grey again, on & on again until i release the keys then start up proceeds as usual, but since none of my control panel settings have changed, and the finder still quits, i dont think that the zap was successfal. Am i missing something? Anyone have any suggestions? BTW I have a B&w G3/350 w/OS9. TIA for any help :-)
