Thanks for the info on this... my first reaction was to just copy files. I never associated an archive with the way to move a game from one place to another - just concentrated on the 'save'.
The game restored fine -- and played w/o changes, but the background color on the command buttons and the info bar at the top changed from the standard black to what appears to be one of the colors I picked for my pieces... (?) Not disabling, but strange.
Thanks, again...
Gary
