Hey Everyone, I'm having a frustrating problem with my Alu iMac 2.8/4g/750. About half of the time I import photos into iphoto, my entire machine locks up. It always happens in the same manner: first iphoto, then the rest of the machine freezes. The mouse cursor still works, and things like video that was playing before the import started will keep going, but I can't kill anything or access the terminal. I thought that the problem was my card reader, an off-brand, but it does the same thing when importing from the camera, a Canon 350D. I'm importing RAWs. I've tried repairing permissions and deleting the iphoto plist file, but nothing helps. I'm considering re-installing the system, do you think that would help? Thanks a lot in advance for your help!
