Mouse Motion Listener

Question

How can i detect when the mose moves when the mouse is not located on the Frame?
Here is my mouse motion listener
private class EventHandler implements AWTEventListener {
          private JPanel myPanel;
          public EventHandler(JPanel thepanel){
               myPanel = thepanel;
        public void eventDispatched(AWTEvent event) {
            if (event.getID() == MouseEvent.MOUSE_MOVED) {
                 MouseEvent me = (MouseEvent)event;
                 myScreenShooter.setCaptureLocation(me.getX(), me.getY());
                myPanel.repaint();
    }and I register it with a JPanel which I extended
Toolkit.getDefaultToolkit().addAWTEventListener(new EventHandler(this), AWTEvent.MOUSE_MOTION_EVENT_MASK);But the only time the motion is detected is when the mouse is within the panel...I need to know when it is moved anywhere on the screen.
Any ideas?
Thanks
