The purpose of CombineZ Movie is to increase depth of focus by combining pictures that you have taken. Each picture should be in focus at a different depth into the scene. It makes life easier if they have been taken at regular intervals, though this condition is not essential. When performing most of the major operations, you will notice the Progress dialog box appears, then disappears when the operation finishes. If you wish to see the Progress box at any other time press F2. The Cancel button in this box may not stop the operation immediately but will stop it at the next convenient point, from CombineZ's point of view.
