I'm not trying to take back the move, because I haven't made it yet. Have you ever clicked a pawn, paused, and then clicked on another piece and moved that one? Thats what I wanted to do, but can't because I couldn't get rid of the promotion screen.
A far better solution than calling for repair of a problem that doesn't exist would be for you to become more disciplined in your play.
I'm not worried about touch-move because there is no such thing in online chess. If there was, thats a different story, but right now thats irrelevant.
