Swing popup in Swing application

I have a Swing UI with a certain number of buttons. One button invokes a separate swing class, and a new window opens with new buttons and other functions. Now, when I close this window, the original window also closes. I think this is because both classes are impedmented

javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
//some code
}
}

Now how to overcome this? A sample code or link will be very helpful. Thanks

It's hard to guess without seeing the code. Perhaps your JFrameinstalled setDefaultCloseOperationto close the application when the window is closed (perhaps EXIT_ON_CLOSE). See the java doc for more information on this.

From java doc :

EXIT_ON_CLOSE ( JFrame): , System exit. .
