iPhone app bug



I was playing a game against someone and it turned into a long, tough game.  I went to make a move from my iPhone app, and I couldn't.  I just couldn't.  I went online and was able to make the move.  Next time it was my move, I couldn't make the move from my phone; it had to be on the computer.

I think it was move 91 when I was having problems.  My opponent and I both thought there might be an upper limit to the number of moves allowed on the iPhone app.

I can't find a version number on the app, either.
