## menu_popup

This is an extra routine which you may never need. It provides a way of displaying information while a process is being performed rather than the script stalling silently. It is called in two forms; first to display the popup and then to remove it;

menu_popup($header,$message)
  This creates a popup which overlays the current menu. A very small window is opened with a drawn border and $header displayed in the centre of the top line. The $message is displayed in the body of the window on a single line (no word wrap is performed on this text - make sure it is only one line long!)./

  After calling this, your script should go off and busy itself until ready to talk to the user again

menu_popup()
  call the same routine with no parameters and the Popup menu will be removed.

Please remember to close the popup as dangling windows can trash your display.
