Keeping a JWindow on top

[Frank Hale]

I created a splash window from a JWindow. I start my JWindow in a thread inside my app so that loading of my app looks faster. The problem with this is that the main window will show over top of the splash window a few seconds after the splash initially shows. I want to keep the splash window on top until it disposes. How can I do that? I've tried using toFront() but I am not getting the desired results.
Thanks,
Frank

Frank,
I have an idea what it might be but would you mind posting the key parts of the code so I can see exactly how you are going about this.

Sure.
Here is the splash window

import javax.swing.*;
import javax.swing.border.*;
import java.awt.event.*;
import java.awt.*;
import java.io.*;
public class MySplash extends JWindow
{
        private Thread t;
        
        public Container container;
        public JLabel label;
        public JLabel version_info;
        public JPanel panel;
        
        public MySplash(ImageIcon logo, Version info) {
                
                container = this.getContentPane();
                container.setLayout(new BorderLayout());
                
                label = new JLabel(logo);
                
                panel = new JPanel(new BorderLayout());
                
                panel.setBorder(BorderFactory.createLineBorder(Color.black));
                
                version_info = new JLabel("Version: " + info.getVersion() + " | Build Date: " + info.getBuildDate());
                
                panel.add(label, BorderLayout.NORTH);
                panel.add(version_info, BorderLayout.SOUTH);
                container.add(panel);
                
pack();                
                
                Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
                int w = getSize().width;
                int h = getSize().height;
                int x = (dim.width-w)/2;
                int y = (dim.height-h)/2;
                
                setBounds(x, y, w, h);
                
                setVisible(true);
                
                try{
                        Thread.sleep(4000);
                        hide();
                } catch(Exception e){e.printStackTrace();}
        }
}

Here is where I open the splash window in my app.

        public void run()
        {
               ms = new MySplash(MyIcons.logo, version);
        }

There is alot more code but I don't want to post it because it will confuse my question. What happens is that the splash window shows when the app is started. About a second after that the main application window shows over top of the splash window. What I want to happen is the main window show behind the splash window. I want to keep the splash window on top of all windows while it is shown.
