Hi Al and others: I apparently was not clear, on my old G4 1.25Dual 800 running OS 10.4.11, I saved all the G4 List to my Hard Drive, which I still have on an external H/D. ( Old G4 Power Supply and Logic Board crashed an burned, mysteriously). This was in Mail and to a Mailbox in Mail. Now on the Mac Pro, OS 10.5.2 and in Mail I can file all e-mail to a mailbox except My G4 List. It will not let me move it. This stumps me, I tried moving a copy, and I tried resending list to me, to no avail. My PowerBook G4 with OS 10.4.11, never had a problem. John
