Okay so I recently purchased the upgrade box set with leopard, ilife09 and iwork 09. After downloading the ilife software, i went to iphoto and discovered that my thumbnails are messed up. In some albums they are all missing(grey box with !) and in others its only some. The strangest thing is that when I first click on the library or a certain album the pictures are there for a split second then disappear. The blank thumbnails have file names and when I double click the empty box the photo comes up full size. So, photos are in there somewhere but dont want to show themselves as a thumbnail. Any thoughts?
