touch move?

is there a touch move system with the chess here? because, whenever i click on a piece i can't unselect it, so i have to click "back" on my browser.

You're move can be changed until you hit the 'send' buttom, you can also use the 'cancel move' link underneath the board

The cancel link appears with the send button (=when the move is finished, after placing the selected piece, and not after just selecting a piece)

thanks
