Thanx "f-erenc szabo" I understand about Logic 7. This is an issue with "Tiger" on a G4 running LPro 6.4.3. I think I'll re-install Panther. That should clear this all up. My G5 w/ Logic 7.02 works real sweat. I think it's an OS issue-unfortunately. I was told by an Apple tech that there wouls be any problems. Whatya goona doooo?!??.................Thanx for responding though. I appriciate it Tigerk
