Server error on Internet Chess Club

The server on the Internet Chess Club doesn't realize when a game is a draw or not in a very obscure situation.

I had a game where it was King and Bishop versus King and Bishop - those were the only pieces on the board. The Bishops were on opposite colored squares. The ICC server declared this a draw -- however, this is only an automatic draw if the bishops are on the same colored squares.

For instance, consider the problem here -- white to move. Black has very foolishly played Bxb8 (instead of Kxb8, it doesn't matter what was on b8), and now White plays Bg2#.

Of course, if we were playing on ICC, the server would stop the game after Bxb8 and say it was an automatic draw.
