This is my first post and I’ve searched for a solution to this issue but can’t find one, possibly because it’s hard to describe, so please excuse me if this is a dumb question.  I’ve imported RAW images (shot at aspect ratio 3:2) into a new Aperture (v3.5.1) project.  So far, so good.  When I view the images in split view, each time I navigate to the next image, Aperture appears to crop a little from the top and bottom of the image, and there’s no way to get these cropped areas back.  This only happens the first time I navigate to each image.  I can’t imagine why this is happening but I’d appreciate whatever help you can offer.
