I managed do everything you said, but I'm not sure I did it in the proper order. I tried a coupe of times. Once the picture stayed "squared up," but some extra space appeared around. Another time, I had to do it again. I'm sure your system works, but would you kindly walk me through your steps. It took me forever to realize the "scale" was a menu item and not an icon. Thanks again . . .
I am starting with this image. (Hopefully your image isn't this distorted)

This next step may or may not be necessary. (If the camera is well set up it might not be necessary)
Use the a tape measure to measure the original frame and determine the aspect ratio. For example, if it is 500x400mm then the aspect ration is 500/400 = 1.25:1
From the menu bar, select (Image > Scale Image)

From the Width and Height, determine the aspect ratio. If it is not the same as the original adjust either the W or H to give the correct aspect ratio. NB Make sure the chain symbol next to the W and H is broken! Click on it if necessary.
Another possible problem (not dealt with here) is that the edges of the frame are curved. This is caused by a less than perfect camera lens. This can be corrected.
