Live 7 will crash for me, when I delete any audio track that has a vst or au plug routed to it. As I am the type of guy who creates my own drums, this means I am " speed deleting " a lot of audio tracks. If they have a vst or au routed to them, live 7 will crash.
macbook pro, os x 10.4.11, 2 gigs of ram, a 7200 rpm hd
I left a log somewhere recently on this board.
Cheers
