;;; THe bug below seems to be fixed in Motif 2.0.1 (Linux RedHat Motif)

;;; Note: some code in this file shouldn't be necessary -- it
;;; works around a BUG in SGI Irix 5.2 version of Motif 1.2.3:
;;; When toplevel window for this app is closed, while tearoffs
;;; are popped up, a core dump will occur. Closing the tear-off
;;; windows first will prevent core dump from occuring:
;;;
;;; indeed-6-.../widgit/examples> dbx `which winterp` core
;;; dbx version 3.18 Feb 14 1994 00:52:47
;;; Type 'help' for help.
;;; Process died at pc 0xf703b38 of signal : Bus error

;;; --------------------

;;; The fix is to prevent the standard window manager destroy from occurring by using the following

;;;	    :XMN_MWM_FUNCTIONS	(logior MWM_FUNC_RESIZE MWM_FUNC_MOVE
;;;					MWM_FUNC_MINIMIZE MWM_FUNC_MAXIMIZE)
;;; also a "Quit!" pushbutton below has a callback which explicitly destroys all the 
;;; pulldown menus first, then destroys the TOP_LEVEL_SHELL_WIDGET_CLASS instance...
