Actually I have been wondering how to cut and paste but I haven't even attempted to do it yet. And I am not sure I can do it with MS Paint.

The only thing I did besides the import/export/save process was to touch up the shields and change the color of the trim in some other segments. Somehow I seem to have accidently converted the alpha background from transparent to opaque. I suspect it happened during the save process but I really don't know.
