I have been having this problem with my G4 since Panther, and I was wondering if any one else had the same problem. When iMovie HD is running, or has recently run, I am unable to launch Apple Works. Some times I can trash AW preferences after quitting iMovie, and it will work. The rest of the time, I have to reboot to get it to work. So, if any one has a chance, try running iMovie HD for a few minutes, then launch Apple Works and see if it crashes. Thanks, Kevin
