Browsing kills applet - how to prevent it?

[Nojd]

I've made a java game that I run in a separate window. No problem. I launch it in a separate window from an applet that simply is a start button. That works well.

But when the browser window with the start button is used to go to some other page, the game window disappears (is destroyed). How do I prevent that?

I'm sure the solution is very simple and has something to do with threads and the Runnable interface, but I haven't been able to figure it out...

A few details:
JDK 1.4

// The applet which simply is a start button
public class HelloApplet extends JApplet implements ActionListener {
  // ...
  public void actionPerformed(ActionEvent e) {
    if (e.getActionCommand().equals(HELLO)) {
      Hello h = new Hello();
    }
  }
}

// The game
public class Hello extends JFrame implements ActionListener, Runnable {
  // ...
  public void run() {
  }
  // This method is run when the Exit button is clicked
  public void actionPerformed(ActionEvent e) {
    if(e.getActionCommand().equals(EXIT)) {
      this.dispose();
    }
  }
}

Thanks!

I thought this would be easily solved, even if I haven't been able to find the solution. Anyone? Please?

In case anyone is interested, the game I made is called Kalaha and is a variant of the African board game Mancala. Here it is:

Hmm, I think it might be a Java security feature. Is your applet signed and made to run as a trusted applet, I imagine if the first applet is stopped and is unsigned, thus untrusted then the second would be stopped and hence in a way destroyed b/c it has been opened by that first applet thus I think that it's owned by the first applet. Like to hear the solution if you figure it out.
