Hi everyone, this is my first post. I am having trouble with iMovie '08. iMovie '08 will not open ( I have the latest iMac, 2.4 GHz Intel Core Duo w/ 10.5.1 ). The iMovie window opens, but everything is inactive until the color wheel starts spinning and I have to do a force quit. I have created a new user account and iMovie '08 opens just fine there. I have re-calibrated the display but no luck. As best I can tell this all happened when I upgrade to Leopard. I can't remember whether iMovie opened when the machine first came loaded with 10.4.
