wxruby users - Nov 2009 - 'Are you sure?' custom dialog not exiting cleanly

The following program does not exit cleanly after pressing
''Yes'' when asked
''Are you sure''?
How do I free up the resources after exiting?  You can use wxsugar (xrcise)
to try out this mini program
if you wish to create sample1.rb .   Thank you.

It looks like you either need to make the confirmation dialog a child of 
the main frame of the whole program, or else call dialog.destroy 
explicitly when you''re finished with it, whatever the return value of 
show_modal

  def confirm_closure
    # dlg = DIA_Frame.new
    dlg = DIA_Frame.new(the_main_window)
    if(dlg.show_modal==Wx::ID_YES) then
       dlg.end_modal(Wx::ID_YES)
       self.destroy
    end
  end
