I'm moving this to it's own thread per your suggestion. Thanks for your concern
I have isolated the problem a bit more:
Record first clip on a track, in either clip or track view in the chooser window = OK
Record another clip on a different track, in either view = OK
Record another clip on the same track, in track view = OK
but
Record another clip on the same track, in clip view = LOCK UP
The lockup happens just after i click on the clip record button - it shows the first little bit of the waveform being recorded and then freezes the screen. I've been doing this with the metronome, so after the freeze i just hear metronome clicks, and can't stop them without killing the program.
I don't have this problem in 2.0.3
Thanks again
