orig synopsis: "Problem restoring a JFrame's size with LookAndFeelDecorated=true"

java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b65)
Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)

The problem seems to happen when maximizing a JFrame with
the property defaultLookAndFeelDecorated=true. Trying to restore the
JFrame to its original size from the restore button will fail.

The problem seeem to occur only with the Metal L&F on Windows 2000.
[Actually, under Solaris, _maximize_ doesn't work, so one never
gets a chance to try (to) restore. --eval1127@eng, 3 June 2001]

A sample code that demonstrates this problem:

import javax.swing.JFrame;
import javax.swing.UIManager;

public class LaF_Frame extends JFrame
{
  LaF_Frame()
  {
    setSize(600,400);
  }

  public static void main(String args[])
  {
    JFrame.setDefaultLookAndFeelDecorated(true);
    new LaF_Frame().show();
  }
}

Run this program. Click the maximize button. The frame maximizes and the
maximize icon in the title bar changes to 'de-maximize'.
Note the following bugs:

1) Clicking on the de-maximize button in the title bar has _no_ effect.

2) When you move the mouse to the window borders the cursor changes to a resize
   cursor (though one cannot resize the window).
[see also bug # 4394457]

3) You _can_ drag the window to another position using the title bar. This
   should not be possible.

I don't think this is platform specific, but maybe part of the problem comes
from my dual monitor configuration:
Windows 2000, SP2, Matrox G450 graphics card in true dual head mode (two graphic
adapters visible in window's settings), latest drivers (v5.52).

import javax.swing.*;
public class MaxFrame extends JFrame {
    public static void main(String[] args) {
        JFrame.setDefaultLookAndFeelDecorated(true);
        
        JFrame f = new JFrame();
               
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        f.setBounds(100, 100, 100, 100);
        f.setVisible(true);
    }
}

The new 1.4 Metalworks demo which uses a PLAF decorated frame demonstrates this
problem. If you maximize the frame, it covers the entire screen even though it
should not cover the Windows taskbar.

Additionally, the frame is still draggable (maximized windows should be locked
in place under Windows), and when dragged you can see that it does not have a border anymore. The lack of a border may or may not be a problem depending upon whether the frame is ultimately locked in place or not.

The frame also cannot be restored (un-maximized) - clicking the restore button has no effect.
