I just got a new 4 core 2.66 mac pro, 5 gb ram (from Crucial). Everything newly installed and updated. MOTION 2 is crashing after about 10-15 minutes each time i boot up the program. And I know the progeam is fine because i didnt experience this when it was loaded on my laptop (although it was much slower there, as you might imagine) I cant seem to nail down any particular action that is triggering it... a couple times i was adjusting keyframes that were animating a size change, once i was scrolling through previews of the particle emmiter library... I went into the drive with Disk Warrior and repaired some directory jumbles, but again, the program crashed. What are my options here??
