One photo in Aperture 3.5 will not go into album
I have a photo, originally a .tiff file that is in my iphoto library and in an album. In Aperture 3.5,the photo shows up in the photos but is not in the album. If I try to drag it from the photos to the album iin Aperturet it does not go into the album. I converted the Tiff to a jpg and the same thing happens. I can inport to Aperture library but cant put it into a album. Anyone have an idea why this is happening?
