I've gotten everything I need from MobileMe but there is no 'Cancel' button to opt out of this migrating. Only 'Learn More' or 'Okay'. After I pressed okay, iPhoto migrated all MobileMe photos out of their original events and grouped them under a new event call MobileMe. Why would it do that? Now I have 10,530 photos displaced from their original parented events and I have no idea how to put them back where they belong. Com'on Apple, *** are you thinking??
