Dear Maintainer,

When I was trying to autosolve an xmahjongg board (board 1), with the s key,
that key did nothing. I tested different board numbers, and found out that it affects
up to board 65535. Boards 65536 and higher autosolve as usual.

To recreate:
``xmahjongg -n 1``
press the s key when the window opens
nothing happens
