I use Aperture 3 on OSX 10.5.8. Suddenly I find that the images in the viewer are shifted to the right, so that the right-hand side of the image is cut off and there's a grey strip down the left hand side. I must have accidentally changed some setting but I can't figure out what ... It applies in all projects. It's the same problem this guy had but it's not clear from this conversation what the fix is: http://discussions.apple.com/message.jspa?messageID=11568440 Edit: also, I find that in Projects view, all the projects are stretched out in one long row left to right rather than in several rows down the screen. Similarly photos in Photos view. I tried the fix of deleting the plist file but when I deleted that and opened Aperture my more recent projects were missing. Luckily I had kept the old one and restored it and got the full library back. Any ideas? many thanks!
