I have a how-to question. When I am moving the location of an area selection tool (say, a fixed-size rectangle), is there a way to require it to always remain in the image area, as if there were a wall around the image that it could not cross? Right now, the selection area can be partly outside the image, but it would be helpful at times to disallow this behavior. I searched this forum, keyboard commands, the FAQ, the Help file, etc, but didn't find anything. Thanks for any information you are able to provide.
