  This timer callback shows a message dialog (fl_choice) window
  every 5 seconds to test "recursive" common dialogs.
  
  The timer can be stopped by clicking the button "Stop these funny popups"
  or pressing the Enter key. As it is currently implemented, clicking the
  "Close" button will reactivate the popups (only possible if "recursive"
  dialogs are enabled, see below).

  Note 1: This dialog box is blocked in FLTK 1.3.x if another common dialog
  is already open because the window used is a static (i.e. permanently
  allocated) Fl_Window instance. This should be fixed in FLTK 1.4.0.
  See STR #334 (sic !) and also STR #2751 ("Limit input field characters").
