Live chess programming BUG!!!

I was winning badly and my opponent disconnected, and then I accidentally closed the window trying to minimize it, and the system resigned automatically for me even though it was my opponent's turn! This is HORRIBLE...must be changed.

On another note, the system should make it impossible to play multiple live chess games at once... i thought i had won a game when my opponent disconnected, and then i started playing a second game, forgot about first game, and with one second left my opponent logged back on an made a move and I timed out...horrible...but i guess that's my own fault

1. You need to look up the definition of "bug"
2. If you close the window (not disconnect), you lose. This is there to prevent people from letting the clocks run in a lost position.
3. If you still want to play, don't close out the window.
4. Why should I not be allowed to play multiple games just because you can't use the feature properly?
