Unless the rules of chess has changed, I discovered another bug. I was able to castle (King moves more than one space to the side while the Rook traverses the King), after getting "Checked" by the opponent. The game won't let you castle while under check, but I thought the rule was that one could not castle during AND after being checked. No big deal to me, it makes the game a little easier but just thought I'd see what others say.
