Thanks for the rapid responses. I am using PT 6.4 with OSX 10.3.2 with a Lacie external Firewire drive that is only for Protools read and write. When I try to open another track, the message says that there isn't enuf .....(cannot remember the exact words). It will load the track, but the last one in the list then becomes inactive. All tracks are mono.
Thanks again for trying, I was all set to up the Ram, I guess that won't help.
