  1. Installed Celestia on my iBook G4 running 10.4.1 but the computer LOCKED UP when I tried running it. After rebooting, apps that are supposed to start up no longer start up. The Action pulldown menu for the Applications folder is corrupted. This software is problematic and destructive. Stay away.
