The problem is that when the JPopupMenu is visible, if an event
disabled the JMenu that has popuped the JPopupMenu. This one will
not be closed when releasing the mouse !

The problem appears with any JDK/Swing version (1.1.8/swing 1.1.1 or 1.2.2 or 1.3)

Here is a an example. To reproduce :

1- Launch the sample
2- Choose "File"
3- Choose "Select This Sub Menu"
4- During the time the sub menu is open, click on the label
in the main window (this will disable the Select This Sub Menu item)
5- The popup IS NOT closed !

To repeat you need to relaunch the sample

////

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

public class PopupProblem extends JFrame
{
  // PopupProblem CJO 09/99
  public static void main(String[] arg)
  {
    new PopupProblem();
  }

  public PopupProblem()
  {
    super("Popup Pb");
    
    JMenuBar bar = new JMenuBar();
    JMenu file = new JMenu("File");
    file.add("...");
    file.add("...");
    file.add("...");
    final JMenu sub = new JMenu("Select This Sub Menu");
    file.add(sub);
    sub.add("---");
    sub.add("---");
    sub.add("---");
    bar.add(file);
    setJMenuBar(bar);
    JLabel label = new JLabel("Click on this part when the sub menu is opened");
    label.addMouseListener(new MouseAdapter() {
      public void mousePressed(MouseEvent e) {
        sub.setEnabled(false);
      }
    });
    getContentPane().add(label);
    setSize(640, 400);
    setVisible(true);
  }
}
