I just purchased iLife '09 and installed on my iMac G5 (1.9GHz, 2.5GB RAM, 160GB HDD). I updated the software to the latest version via Software Update. When I launch iMovie '09, the program appears to load, but when I try to do something (i.e., click a button), I get the spinning beach ball and have to force quit the program. Tried repairing Disk Permissions and such. No effect. Any ideas on how to get iMovie working fully? Thanks!
