Thanks Alan.  Your instructions were very clear and it ran smoothly.

OK Fred, unzip the test files, keep them together in a folder that you can
easily find somewhere on your PC.

Start CombineZM.exe.

on the File Menu click New.

A file selector should open, navigate to and open the folder containing the
test images.

Select ALL of the images, then click on Open. All of the files should be
loaded, you should see one of them on the screen. If you want to see the
others use the Up and Down Arrow Keys.

On the Macro Menu click on Do Stack, the main window will be hidden, it will
reappear when the frames have been stacked and you should see the result on
screen.

Notice the result has rather odd looking edges these need to be cropped off,
either in another program after saving the result with Save Frame/Picture As
... Or you can crop and save in one go by using Save Rectangle As... The
rectangle saved is the contents of the dotted box, try pressing 'A' and
watch the box move in, or drag out a box to include just the part you want
to save then Save Rectangle As.
