MIDLet.destroyApp() and turning back to applications screen

Question

Hi all,
When I choose exit in the code develivered with the Wireless Toolkit the screen returns to a screen filled with available MIDlets. When I choose exit in my application, the screen stays like it was in my MIDlet. How come?
Some code to clarify. First the Canvas class
   public void keyPressed(int keyNumber) {
         if ((keyNumber == KEY_POUND) || (keyNumber == KEY_STAR)) {
              // User wants to quit.
              myGame.closeConnection();
    }As you see, a method in myGame is called. MyGame implements Runnable. It communicates using Bluetooth with another MIDlet:
     public void closeConnection () {
          try {
               ins.close();
               dins.close();
               outs.close();
               douts.close();
               connection.close();
          catch (IOException ioException) {
               displayMessage("IO Error", "Unable to close " +
                         "the connection (IOException: " +
                         ioException.getMessage() + ")");
          finally {
               synchronized(this) {
                     isGameCompleted = true;
                     notifyAll ();
               myMIDlet.destroyApp(true);
     }And again, another class is called. This class, MyMIDlet contains the following destroyApp method:
    public void destroyApp(boolean unconditional) {
    }When I look at the example code (%WTK24%\apps\Demos\src\example\manyballs) delivered with the Wireless Toolkit is see the following code (first ManyBalls):
    public void destroyApp(boolean unconditional)
            throws MIDletStateChangeException {
        canvas.destroy();
    }The following code is called in the object ManyCanvas. It deletes all created balls:
    void destroy() {
        // kill all the balls and terminate
        for (int i = 0; i < balls.length && balls[i] != null; i++) {
            balls.stop = true;
// enable the balls to be garbage collected
balls[i] = null;
numBalls = 0;
So, how does it go back to the screen containing all the available MIDlets?

Try resetting the iPhone. Hold the Home and Sleep buttons until the Apple logo appears.
