When it crashes, does Panther come up with a notificatin saying the program has quit unexpectedly and offering to send a report to Apple? If so, ask it to produce the report. Don't send it to Apple as they probably don't care, but copy and paste the crash log in the report to a post here and we'll see if it gives any clues ... tomorrow, it's way past bedtime in the UK now.michaelkottler said:I replaced the files as advised and now it crashes as soon as it reaches the 4000bc start screen. Hmmm. Any hints?
