hi
i have just updated to the latest version with an undo botton added in it (makes easy to win the game now)!!

there is some problem in new version i think.i was playing qthello today human vs computer with medium difficulty(mine was black) and when the game was about to finish , it was my turn.but there was no place for me go ahead(in older version there was a massege pop saying "black can not move white's turn" in the situation) but in newer one there was no massege and the game is stoped here!! has anyone found same thing???
