My newsreader (Knode) did that. Also, if I don't check c.l.j.p in a few
months, I'll see the reply in a.2600.

Thanks! Will get started.

Thank you - I did this and ended up with something bizarre.

The first frame is loaded twice.

Of course, then the button on the second frame doesn't seem to work.

Ideas??

I'll post the code inline, since the classes are not that long.

frame1.java

import javax.swing.*;
import java.awt.*;
import javax.swing.border.LineBorder;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class frame1 extends JFrame implements ActionListener{
       
       frame2 frametwo = new frame2(this);

       private static frame1 mainForm = new frame1();

       public static void main(String args[]){
               new frame1();
               
       }

       public frame1(){
               
               frametwo.setVisible(false);
               setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
               Container content = getContentPane();
               content.setBackground(Color.white);
               content.setLayout(new FlowLayout());
               JButton button1 = new JButton("Click Me");
               button1.addActionListener(this);

               JLabel lblOne = new JLabel("                  ");

               lblOne.setBorder(new LineBorder(Color.green, 3));

               content.add(lblOne);

               content.add(button1);

               JButton button2 = new JButton("Exit");
               button2.addActionListener( this );
               content.add(button2);
               this.setSize(300, 300);

               setVisible(true);
               
       }

       public void actionPerformed(ActionEvent e) {
               if (e.getActionCommand().equals("Exit")) {

       
                       System.exit(0);
               }
       
               if (e.getActionCommand().equals("Click Me")) {
       
                       frametwo.setVisible(true);
               }
       }

       public frame1 getMainForm() {
               return mainForm;
       }
}
