iPhoto '11 with corrupted Places
I've got a weird situation occurring in Places - where multiple images (100+) which were originally "tagged" in separate locations are now referencing the same incorrect name and location. When I try to delete this errant place in "Manage My Places", iPhoto is non-responsive and I have to Force Quit. Curiously, if I navigate through the Places drop-down menus (Country, State, City, Place) - the original place name exists in the place setting - however when I choose it the tag in the "map view" has the errant name - not the correct name.
Is there any way to restore or "clean up" the Place metadata? I've been using iPhoto since the early days ('04) - always backing up and upgrading. This is the first major quirk I've had in my library of 20,000+ images. Also never rebuilt a library - is that something I need to try? If so, how?
Thanks
