A commercially made CD is "hung" in the drive (plays fine in my vehicle though). Even when it spins up (usually only upon waking from sleep) I still don't get an icon on the desktop so I can't drag it to the trash to eject. Also, neither drop down "eject" nor command E will work. Is there a manual eject button or some sort of magic command?? (PowerBook G4, OSX 10.5.8)
