If there are 2 dialogs (JOptionPane.showMessageDialog(..)one 
after the other in an application (such as what happens with
the JFileChooser example in SwingSet),when the first is dismissed, 
the focus moves a component in the main app (such as JMenu or 
JTabbedPane), then to the button in the dialog and then BACK to 
the Component in the main app. It should remain on the button 
in the dialog since that is where keyboard input is directed. 
This is a SERIOUS problem for assistive technology trying to 
identify and speak the correct location of where input is directed.
Here a code sample to show this.. notice you need to have
the EventQueueClass loaded via the awt.properties and the line:

AWT.EventQueueClass=com.sun.java.accessibility.util.EventQueueMonitor

If you do alt-O to get to Options menu item and then activate
the 'Use this' menu, you see the message dialog, dismiss this,
and you see the second.. check the output of where focus is to
see the problem.

I am trapping a focusLost event and popping a Dialog in that method.
When I pop the Dialog, the focusLost method is getting called again,
which pops a second Dialog.

Here is the code:

class LossDateListener extends FocusAdapter{
         
  public void focusGained(FocusEvent evt)
      {System.out.printnl("Focus Gained");}
                
  public void focusLost(FocusEvent evt){
                   
     System.out.println("Focus lost");
     String dateText = lossText.getText();
     DateRules dateRules = new DateRules();
     String status = dateRules.validateLossDate(dateText);
     if(!status.equalsIgnoreCase("OK"))
         JOptionPane.showMessageDialog(mainFrame, status,
                 "Invalid",  JOptionPane.INFORMATION_MESSAGE );
       
   }
            
}

I get two Focus lost messages and two Dialogs on top of each other.  
When I dismiss the dialog showing on top, the focus lost method
is called again which pops another Dialog.  So, I am trapped 
with unstoppable dialogs.

I am running this on WinNT4.0 service pack 4 and Win98
jdk1.1.7 or jdk1.2
jfc1.1.1 or the one with jdk1.2
