Disable a frame before dispose

Question

if("Back".equals(e.getActionCommand()))
{
    escape.setVisible(false);
    paused = false;
    running = !running;
    Graphics g = start.getGraphics();
    g.dispose();
    Component glassPane = start.getGlassPane();
    glassPane.setVisible(!glassPane.isVisible());
    Main.main(null);
    Main.running = true;
    start.dispose();
}

This is my code for disabling my jframe, loading a new one, and disposing it. Whenever I do this, when I return to the frame I get strange graphical errors. One of the graphical errors!

How do I close the frame completly?

Can you upload that strange errors? And one advice: Don't load a new frame, make your game so you can load a new panel. — Branislav Lazic, Sep 08 '12 at 12:32

Why do you dispose the graphics, did you create it? The rule is always that you dispose what you created. Also, I suppose that `start` is a JFrame. It's unlikely that you need to call `getGraphics()`,... ever — Guillaume Polet, Sep 08 '12 at 12:38

create private/public(depends of your code design) variable for JFrame instance
then you can't bothering with dispose of visible JFrame and then re_create a new one
create class or local instace that returns JPanel with game content
call JFrame#getContentPane#removeAll()
call JFrame#getContentPane#add(new GamePanel())
maybe there are easiest ways how to reset whatever (depends of your code design) to the start_up statuses
