Follow up on this issue:

I have a main-window that has a button to show all details for a 
selected item in a list.

The window is defined as: public class ViewDetails extends JDialog {

The constructor opens this as modal=true;

While testing I had the ViewDetails opened over the main-window when I 
selected to clear the desktop (i.e. no windows open). I then clicked in 
the bottom toolbar to swap back to application and here is where the 
problem occurred:

The process came back but the main-window was in front of the ViewDetail 
window (that is smaller than the main-window). Since it was running in 
modal, I could not move the main-window or get to the ViewDetail in any 
way.

The way I got around this was to open another window (my browser) and 
then the VIewDetail was put in front of the main-window. I minimized the 
browser and could continue with my app.

Now, I can't write in the manual "if you can't see your window - open 
another application and the window will appear ..."

Anyone has a solution for this behavior?

Submarining modal windows are a problem with many Windows applications. 
  This is not necessarily a Java-specific issue.  I find a lot of 
install programs do something similar.

I generally use "Alt-Tab" to find these sorts of "hidden" windows, not 
opening another application...

You need to investigate/google focus issues and z-order issues with 
modal windows/dialogs.  These things tend to be very application 
specific, so a solution that worked for someone else may not work for 
your application.

Thanks Lori,

The Alt-tab works fine and is something (in my mind) that can be put 
into the manual as a "global" solution.

For the re-focus issue I will start with a flag that is set true/false 
from the dialog (or any type of window) and tested on before open a new 
window.

I will attack this later in more detail.

Returning to my old problem.

For now I have solved this with a flag that is set when the window is 
opened and reset upon close. I then test on its flag before open a "new" 
window every time.

To be able to reset the flag I added :

setupWindow.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent we) {
      setMyFlag(false);
     }
});

This works great if the "x" in the frame is used to close the window, 
but, I have added a "close" button in my setupWindow and the actioncode 
there is:         this.dispose();

Now that doesn't bring me to my listener above so I must make my flag 
static and I call setMyFlag from the close-button.

Can I use something else than "this.dispose()" to get the same action as 
for the "x" in upper frame menu?

Thanks for any help and hints.
