Windows open effect in Java only happens once

Question

Hi,

This is not a huge problem but I am wondering if there is a solution. In the example below a window opens with a button and if you press that button another window opens, in Windows 7 it does a little effect when it opens. When you close the new window it does another effect for closing. If I press the button again it just pops up without the effect. Is there a way to fix that so that the effect always works without re-creating the frame?

import javax.swing.*;
import java.awt.event.*;

public class asd
{
    private static JFrame frame2;
    public static void main (String[] args)
    {
        frame2 = new JFrame();
        frame2.setSize (500, 500);

        JButton button = new JButton ("Button");
        button.addActionListener (new ActionListener() {
            @Override public void actionPerformed (ActionEvent e) {
                frame2.setVisible (true); } });

        JFrame frame = new JFrame();
        frame.add (button); frame.setSize (500, 500);
        frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
        frame.setVisible (true);
    }
}

I don't have a Win7 box so this is just another guess.

qmega's comment is probably the reason, so the answer could be calling dispose() then pack(); setVisible(true) in your action handler.

Ref Window#dispose javadoc.
