Have Chess.com considered adding a button for undo or take back. In several games I was using my laptop and the piece falls from the mouse before I get to the intendded spot. It cost me the game each time. Perhaps there should be a 5 second delay before the piece is accepted in a square.
When you factor in my arthorghtist, this places me at a great disadvantage.
Have other players complained about this? Is it possible for a skilled computer person to cause the pieces to drop from the opponents mouse?
