I have created a popup menu to be posted via button press
(exactly as in the Motif Programmer's Guide) on four
FormDialogs and the application MainWindow.  Each FormDialog
may or may not be managed, but each has a single custom-widget
child (I'll call Plotter).  The MainWindow has a Form widget
for a workarea, and that Form also has a Plotter child.

The popup menu was created as a child of the appshell returned by
XtInitialize.  The popup menu should post on BP from any of the 
Plotter widgets; i.e. I want the same functions to be supplied each
of the five Plotters.  The same managing callback is added as an
event handler for all five Plotter widgets.

The problem is that the menu won't post in the MainWindow;  I
get a right-pointing arrow with a BP (Button3, which PostPopup looks
for) everywhere in the workarea of the MainWindow.  (Do I need to
explicitly set the Form child using XmMainWindowSetAreas?)
However, the popup posts fine with any of the FormDialogs.

What seems to be bizarre is that once I have selected a button from
the popup menu (i.e. activated a callback from the popup), the
menu posts normally in the MainWindow, and I no longer get a right-
pointing arrow elsewhere in the MainWindow.

Help appreciated, trivia maybe.
