I went back to that defunct library, and control-clicked upon that huge exclamation point, it just went back to the thumbnail. No menu showed up.
Interesting that the original photos could not be located by iPhoto, they are all there, I created a new library from the old one and this one is named iPhoto, recreated library.
It now works fine, though I would love to be able to get rid of the old ones. When I open iPhoto and hold down the option key, I can choose the new libraries.
All the pictures are there on my hard drive thank god!
Looked up how to disable Faces, it only grinds away on a couple of my iPhoto libraries, not on all of them. Listening to my hard drive chug looking for faces, which I do not use, is not what I want. I saw this as an annoying feature on a few forums too.
Thank you for explaining this! I tried to fix the thumbnail database or whatevertheycallit, and that didnt work either, I just took the folders of old photos and dragged them into a new iPhoto.
