def initialize *args
  super(*args) # we do always get here...
	 # because we do this, you should *not* have to call the unsafe:
	 # setDefaultCloseOperation(EXIT_ON_CLOSE)
	 # which basically does a System.exit(0) when the last jframe closes. Yikes jdk, yikes.	 
	 #addWindowListener(CloseListener.new(self))
  dispose_on_close # don't keep running after being closed, and prevent the app from exiting! whoa!
