An aperture photo edited in PE 12 is saved after editing in Aperture. However, the edits are not saved. The only workaround that I have found is to save the PE 12 edited photo to the desktop and then import it into Aperture. This is unacceptable. My current version PE 8 works correctly, i.e., open edit an Aperture photo automatically in PE 8, edit the photo, save the photo and all edits are correctly applied in the Aperture photo library.
