I've found some photos cause the iPhoto 'Assembling' phase of ordering prints to freeze so so that the iPhoto still shows, but is otherwise unresponsive to the point that only Force Quit can quit. This has caused a couple of apple crash reports, but not consistently.
Cropping the photos seemed to allow the assembly phase to work. I don't want to spend my days cropping.
Does anybody know what is wrong with my photos, and if there is a non-crop fix?
