[QUOTE="Daniel Pitts, post: 2025730"] Ah, I see the problem... doRoll blocks until dieTm.stop() is called... The problem is, that the Timer event won't be able to be dispatched until doRoll returns, which means that actionPerformed won't be called, which means dieTm.stop() won't be called, which means... DEADLOCK! public int doRoll() { setVisible(true); counter = 0; dieValue = (int)Math.ceil((Math.random()*6)); dieTm.start(); return dieValue; } public void actionPerformed(ActionEvent e) { setIcon(dieImg[(int)Math.ceil((Math.random()*6))-1]); counter++; System.out.println(counter); if (counter == 10) { dieTm.stop(); setIcon(dieImg[dieValue-1]); return dieValue; } } [/QUOTE]
