John I’m having the exact same issue. I was merely trying to “play around” and get a feel for it. As soon as I applied a filter everything would slow down, as I continued to work everything locked up and it took five minutes just to force quit. I sure hope they get this fixed because Final Cut 7 looks better by the minute. Quick question though. I’m running Final Cut X on the road on my 13″ MacBook Pro 2.26 Intel Duo 5GB RAM. I’ve never had any problems with running multiple programs including Final Cut 7, Motion, AE and Photoshop at the same time. I now only have Final Cut X open and having all these issues. I know my computer matches the specs, but I’m wondering if I’ll always have problems running it with this model. Thoughts?
