Help please !! I'm running 10.3.9 on a 1.5ghz G4 Powerbook with 1GB DDR SDRAM, and today whilst working with iMOvie the whole show slowed to a crawl. It is impossible to edit anything as the catherine wheel just spins. Can't play a movie (thorough iMovie either) as it is slow and jerky. (iLife04). The whole system has slowed. I recopied iMovie from my external hard drive backup and it worked once and now has returned to dead slow. Recopying doesn't help. I had a similar problem a while ago when iMovie died and wouldn't open, but restored the whole operating system and it worked. I don't want to go through that again as I had SO many problems reloading downloaded software and getting the printer to work. Someone said I may have problems with the hard disk. I've repaired all the file permissions and now don't know what to do. Please !!!!
