Defective mouse

Can you pls add a destination square that a player can type in, e.g. B-g4, instead of guiding the mouse to that square? So that a defective mouse will not decide the result of a game by dropping-off a piece on the wrong square thus giving-away the piece for free.

It becomes frustrating particularly during a crucial part of the game when one loses his piece because of a defective mouse. 

Can you pls add a destination square command in your program.
