I’m on a Mac g5 with PSCS4 and a Leica M8. I've been shooting with the M8 for about a year -no problem. I downloaded images with no problem this morning. This afternoon I downloaded some images and the thumbnails showed up in Bridge with a black border on the long side of the thumbnail. When I clicked on the thumbnail image it opened up in Preview as a large thumbnail with the black border. not the full image as it normally does. If I repeatedly click on the Preview image it will get a little bigger but not like the normal Preview image should be.
Any suggestions
