I have only been a MAC /Logic user for about 6 weeks. Coming from the PC world, and being a former Audtion and Cubase user, at first I hated Logic but now I'm starting to really, really enjoy it. Since my version of Logic Express did not come with a secret de-coder ring, I've had to rely on a lot of great info here which has helped tremendously. I have also burnt out my retinas endlessly scanning the manual. The environment is still a huge mystery to me but, otherwise, Logic is great to work with. I recently updated to 7.2.1, as well as OSX 10.4.9. I now find that about 1 out of every 5 times I try to open LE, I get a "Logic has failed to open" message and I must force quit to close it. A restart always returns all to normal. The last time this occured I also tried to open Garageband after force quiting LE. GB gave me the same message. This only seems to happen with LE/GB and no other app. Perhaps it is an OSX issue and, since I am a noober for both Mac and LE, perhaps its a dumb user issue. In any case, any thoughts or suggestions for a solution would be greatly appreciated. I have an 20" 2.16 Intel core 2 iMac, 2 GB RAM, 160 GB LaCie external HD.
