No frame refreshing when buffered window is called/created

Question

Hi,
i'm programming a java-based game. It uses a JFrame that calls an "accelerated window" ( a buffered window with a Graphics2D Object ) to draw a basketball simulation. The problem is that when the accelerated window is running ( loop ) the refreshing and the listeners of the main window doesn't work properly (note that accelerated window is called by a Game class that extends Thread... ). Why? Thanks
// Class Game is called by a main JFrame...
public class Game extends Thread {
    public Game( ... ){
     court = new Court2D();
     court.setVisible(true);
     court.draw();
public class Court2D extends Canvas {
        public Court2D() {
         container = new JFrame("Court");
         container.addWindowListener( new WindowAdapter() {
              public void windowClosing( WindowEvent e ){
               container.dispose();
         JPanel panel = (JPanel) container.getContentPane();
         panel.setPreferredSize(new Dimension( WIDTH, HEIGHT));
         panel.setLayout(null);
         setBounds(0,0, WIDTH, HEIGHT);
         panel.add(this);
         setIgnoreRepaint(true);
         container.setResizable(false);
         container.setVisible(true);
         requestFocus();
         createBufferStrategy(2);
         strategy = getBufferStrategy();
         draw();
        public void draw() {
                 Graphics2D g = (Graphics2D) strategy.getDrawGraphics();
             ... //draw something...
             g.dispose();
             strategy.show();

Ops I'm sorry. There's a run() method as you can see as follows:
public class Game extends Thread {
    public Game(...){
         //initiate variables...
    public void run() {  // Called by the main window
     if (quarter == 0)
         jumpBall();
     while ( ( quarter <= 4 ) && !(timeout)  ) { // game loop
         while ( ( timer < DURATION ) && !(timeout) ) { // quarter loop
          step(); //Move
          checkfouls();
          timer = timer + 0.1;
              try {
               Thread.sleep( GAMESPEED );
              } catch (Exception e) {}
         minutes = (int) timer / 60;
         seconds = (int) timer % 60;
         quarter++;
         timer = 0;
         restartAction();
         if ( (quarter > 4) && ( statistics.stats[USER].score == statistics.stats[CPU].score ) )
          ot = true;
         else
          ot = false;
// other methods
}Ok, this Thread never stops and the main window never responds to any type of command ( Listeners included ). Is this strange? This Thread sleeps for a second ( or more ) every loop step but nothing happens in the main window...
