hello ppl, my iphoto keeps hanging. I import my photos and video clips into the library. and i must have done some renaming and moving around in the finder. When i go into iphoto, it will show up a msg sth like "***.mpg cannot be found", then hangs. i know i should have let iphoto take care of my photos, but i'm pretty meticulous. and another reason i thought i could rename the files without worrying is because i thought the "journaled" mac ox format allows exactly just that - moving files around without worries. guess i was naive. so, any help with my hanging iphoto please?
