This it only for people who are running a DUAL Monitor system.

I wrote a sample program to display what occurs.

No matter which button I click on (Primary Display OR Secondary Display),
the JOptionPane will pop up on the Primary Display.

What I would like to happen is...
If I click on the button on the Primary Display, pop up JOptionPane on the Primary Display.
If I click on the button on the Secondary Display, pop up the JOptionPane on the Secondary Display (instead of the Primary Display).

1. How can I get the JOptionPane to pop up on the Secondary Display, when initiated from the JButton on the Secondary Display?
(AND keep the JOptionPane pop up on the Primary Display when initiated from the JButton on the Primary Display!)
OR
2. Do I have to create a JDialog to mimic the JOptionPane to pop up on the Secondary Display?

1) that was (I'm sure that closed) bug about JPopupMenu


2) add parent is always safiest way how to do ... whatever

JOptionPane.showMessageDialog (myParent
, "Test Message #" + j_F
, "Message Title #" + j_F
, JOptionPane.INFORMATION_MESSAGE);

otherwise is JOptionPane dispayed on 1st. device to the CENTER location


3) some profesional GPU have got 2cores GPU, then GraphicsConfiguration[] for two GPUs in SLI mode returns 4 devices

Option #2 is exactly what I was looking for.
So simple. Thank-You mKorbel!!!
