interrupt sleeping thread by mouse action

Hello, I'm developing a computer desk game like checkers (swing application). Now I can't solve up one of my last problems. I have to implement user-user, user-computer and computer-computer game. The first two of them are simple and the last, computer-computer, is problem to me.
My application has menu and toolbar, where the settings of the game items are set up. If I choose computer-computer game in settings, everything is correct. Computer starts to play and answers again. But If I want to interrupt the play, it is impossible. I'd like to click the button in the toolbar, or the item in the menu bar, but the game won't let me nor click the button neither expand the menu.
I have written something like this:

Code:

---

// loop while one of the players isn't set to 'user'
while(!(getPlayer1().equals("user") || getPlayer2().equals("user"))) {
    Thread.sleep(4000);    // time for interrupt computer-computer game
    String[] bestMove = generateBestMove();    // generate best move with given difficulty
    move(bestMove[0], bestMove[1]);  // put the move through
    repaintBoard();    // repaint the board
    if (Referee.checkGameEnd()) {
        break;
    }
}

I need to interrupt this game by click the button. How can I put it through? Thank you.

Calling Thread.sleep will only put the entire application to sleep. If you need to slow the steps of the computer-computer game, I'd get rid of the while loop and instead use a Swing Timer.

Oh... ok, I'll try. I hope I can handle it :-)... thank you.

Edit, also, if you want to stop the logic by mouse button, then you'll need to pause the timer on button click by calling stop() on the Timer.

Whoopee :-)... thank you very much. It's done :-)

Wonderful and congrats!
