	You're right -- thanks.   It's Motif1.1, and we have the right
	version of the toolkit.

	The widget hierarchy:

		toplevel -> bulletin board 0 -> bulletin board 1

	                         |
				 |
			         |
				popup menu with
				quit button

	Bulletin board 1 has a destroy callback registered.
	The quit callback does something like this

		.....
		XtDestroyWidget(bulletin board 0);
		exit;

	The destroy callback with bboard 1 does not get called.
