[note: menu items tend to go away OK, but the menu name (item in menu bar) tends to stay selected/hightlighted after about 2 out of 3 dismissals
of the JFileChooser, IF the total menu length is greater than the height of the enclosing JFrame. Stil present in 1.2.2RC1, so changed release
to 1.2.2 --kevinr@eng, 5/31/99]

if the JFileChooser dialog overlays the menu which brought the dialog up and the frame is taller than the menu, the menu is not erased when the dialog is dismissed.
if the frame is shorter than the menu, the menu is erased.
if the dialog does not overlay the menu, the menu is erased.

after the dialog is up, click cancel. I've removed all the code behind the open.

see code below:

package Bugs;

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

public class UTDFMain extends JFrame {
  private JMenuItem openMenu;
  UTDFMain thisFrame;

  private boolean readConfigFile()
  {
    JFileChooser fc = new JFileChooser( System.getProperty( "user.dir" ));
    fc.setDialogTitle( "Open Configuration File");
    int fc_val = fc.showOpenDialog( thisFrame );
    return false;
  }

  public UTDFMain()
  {
    super( "utdf" );
    thisFrame = this;

    JMenuBar menubar = new JMenuBar();
    JMenu fileMenu = new JMenu( "File" );
    openMenu = new JMenuItem( "Open" );
    openMenu.addActionListener( new ActionListener(){
      public void actionPerformed( ActionEvent evt ){
        if( readConfigFile() ){
        }
      }
    });
    fileMenu.add( openMenu );
    fileMenu.addSeparator();

    JMenuItem exitMenuItem;
    fileMenu.add( exitMenuItem = new JMenuItem( "Exit" ) );
    exitMenuItem.addActionListener( new ActionListener(){
        public void actionPerformed( ActionEvent evt ){
          System.exit( 0 );
        }
      });
    menubar.add( fileMenu );

    setJMenuBar( menubar );

    JPanel mainPanel = new JPanel();
    //mainPanel.setPreferredSize( new Dimension( 450, 20 ));

    //mainPanel.setLayout( new BorderLayout() );
    setContentPane( mainPanel );
    setSize( 450, 170 );

    // with the default flowLayout for a JPanel

    // with setPreferredSize, pack. if height of frame is bigger than
    // menu height, menu is not erased (450, 50)
    // if height of frame is smaller than menu height (450, 20) , menu is erased

    // with setPreferredSize, no pack, => no body.

    // with setSize, no pack, height smaller than menu (450, 70), menu erased
    // if border is grabbed and frame made bigger by dragging, menu not erased
    // with setSize, no pack, height bigger than menu (450, 170), menu not erased


    // with a border layout

    // with a setPreferred size on the mainPanel:
    // without pack, there is no body, not even a menu bar.
    // didn't try with pack.

    // with a setSize
    // without pack, file menu is not erased.
    // with pack, there is no body to the frame; file menu is erased.
    // if one grabs an edge and expands the frame, then the file nenu is
    // not erased.
    //pack();
  } // public UTDFMain()


  public static void main( String[] args )
  {
    UTDFMain f = new UTDFMain();
    f.setVisible(true);
  }
}
