oh wow! After searching off and on for a few years ... and then big time right now ... I found a copy of one that just might work ... "ultimate mahjong" at
http://www.ultimate-mahjong.com/ .... I tried out the demo and it seems to work just fine ... $20 ... i made a real quickie tile set and played several different layouts.... I think I am going to buy one copy ... try it out big time ... then maybe buy my mom a copy so I can send her tile sets. Thank you!
