My library in iPhoto is currently hanging all the time and showing grey boxes in place of the photos. This has now been going on for about a month and seems to be getting worse all the time. It started when some files that were in trash began re-showing themselves as being in the library but as the grey boxes. I re-deleted them and then could not delete them from the Trash. After several attempts it seemed to work, but now I have grey boxes everywhere. My machine has also crashed and required a re-build in that time and I just moved the iPhoto libary folder over to the new machine. I am beginning to think that I have a corrupted library folder and am therefore going to have to manually pull out the contents off all the folders and move them to another folder.. I think that the quickest way of doing this is to do a photo search for photos of size greater than 500K (therefore excluding thumbs), selecting the lot and moving them to a temporary folder. Deleting the iPhoto library folder and then re-import them into iPhoto... I could wait until I get my MBP to do this as I am sure that it would be much quicker, but I really do want a clean build to move over and not a corrupted library. Any thoughts before I rush in?
