I keep experiencing a strange behavior of the crop setting rectangle marker. It often happens in the latest beta (I experienced it in earlier versions as well) under MacOSX 10.5.2 that when I move the rectangle of the crop selection it automatically resizes (shrinks) when pulled to the bottom edge of the image. I usually have preview window on full screen info and filmstrip bars hidden. It is not a great problem doesn't cause a real delay in work just a strange behavior I don't really understand. Maybe an unintended malfunction or maybe an intentional feature I don't understand?
