I’ve been having a similar problem and haven’t yet found what’s going on. I’m on a new 2Ghz dual core PowerMac with 4.5 GB of RAM and the stock Nvidia 6600 LE card (until I can upgrade to the 7800 GT). On occasion, Motion immediately quits or locks up with the spinning color wheel on occassion. I haven’t been able to determine a pattern yet. Sometimes it happens when I’m clicking through the effects (behaviors, filters, emitters, generators), and other times when I try to apply various effects.
BTW, I’m also running the latest Motion 2.01 that was packaged with Final Cut Studio and it’s splash screen does not have a version number either. I thought it was weird too. What’s equally strange is that the version number shown in my About Motion window is still showing 2.0. And I’m sure that I’ve upgraded to 2.01. ???
This forum is my first stop, so I’ll be scanning all the other Motion forums I can find. I’ll post again if I find anything out.
