Crash on stop recording

Thanks for the tip, that's a great website but unfortunately even after following all the advice I could find, the problem persists. It makes GB virtually useless now since 8 times out of 10 the whole thing crashes after recording, losing what I have just done! Looks like I need to look for another sequencer.

Hi Wai Keung - had any luck with our problem yet? I was wondering if it might have something to do with my midi setup. I am using a Korg PA-50 keyboard which is connected to the Mac via a midisport 2x2 USB midi interface. So far I have only notice the problem while recording software instruments. Do you have a similar setup? Just seems strange that we are the only two on here that are experiencing this problem. Also, I notice you are from Hong Kong. I'm based in Malaysia - it's just possible we might have got hold of some dodgy software that is so common over here.

OK I did that. The same thing happened in the new user account. The usual pattern is that I can record one track (usually a piano riff) with no problem. Then when I add a bass line on a new track, the problem starts. I go to stop recording and the track remains red, the screen freezes and I get the rainbow wheel of death. Previously I left it for about 30 minutes to see if it would sort itself out but it didn't.
