I’ve got 10.5.6 too…well..thanks for that! As it happens..after i had that problem i just shut down and started all over again and guess what….?? It started behaving!
Was really pissed off though cos i spent top dollar for the Digital Juice stuff and if i wasn;t going to be able to use even 2 of the clips i was going to end my affair with FCP.
For now, though..we are back in the saddle, hoping that that was nothing more than just a lover’s quarrel.
