Images are blank when editing or viewing full size
In a new iphoto library I imported images (dragged a folder onto the iphoto icon). This brought in what appeared to be the images but it seems it's only the thumbnails. I can see the images within the events and in the list of photos. However when I double click a photo, nothing happens. If I click edit, I have the thumbs across the top but a black screen below. If I click a photo and select Full Screen from the the View menu, I also get the thumbs across the top and a blank/black screen.
Any ideas?
