Opening new frame in new thread

Question

I am having huge problems with an app. The main frame has a button on it. when the button is selected a second frame opens. I would like this frame to open in a new thread and the main thread to wait until it is closed again, but nothing I do seems to work! Does anyone have any ideas?
I have the following code, but the problem is that it prints HAVE FINISHED before the Settings frame is closed:
isRunning = true ;
Thread settingsThread = new Thread()
     public void run()
          Settings sett = new Settings() ;
          isRunning = false ;
          System.out.println("stopped") ;
settingsThread.start() ;
while(isRunning)
try
          System.out.println("sleeping") ;
          Thread.sleep(0) ;
     catch (InterruptedException ie)
          System.out.println("PROBLEM") ;
     } // end while
System.out.println("HAVE FINISHED") ;

Hi,
it sounds like you are looking for a model dialog. If "Setting" inherits from JDialog you can use the constructor "JDialog(this, true)" in your frame of the main app. The problem in your code is, that event handling always has its own thread. You can't permit "running" the window in the background, but you can permit getting the focus with modal dialogs.
