OK, so I updated one of 3 Macs to iPhoto 11 (including the recent patch, before ever launching iPhoto). Everything went smoothly... Until the Mac with iPhoto 11 began syncing with MobileMe Gallery... Now, my MobileMe Gallery has duplicates of every photo (1000's of them)... The local iPhoto libraries on all 3 Mac's (2 - iPhoto 09 and 1 - iPhoto 11) appear to be fine... IF I WERE A BETTING MAN... I would expect that when I update the other 2 Macs to iPhoto 11 the problem will be worse with 1000's and 1000's of duplicates of all photos... OR, EVERYTHING WILL BE OK and everything will sync back up... Any thoughts (or takers) on this outcome?
