Ah! That's the lead I am looking for. I'll switch it all over to
CLEANUP specified for XMANAGER rather than the KILL_NOTIFIES.

The documentation is pretty clear that the CLEANUP callback routine
supercedes the KILL_NOTIFY routine.

From XMANAGER online help...

CLEANUP
Set this keyword to a string that contains the name of the routine to be
called when the widget program dies. If this keyword is not specified,
the routine (if any) specified for the program's top-level base by the
KILL_NOTIFY keyword to WIDGET_BASE or WIDGET_CONTROL is used.
The routine specified by CLEANUP becomes the KILL_NOTIFY routine for the
widget application, overriding any cleanup routines that have been set
previously via the KILL_NOTIFY keyword to WIDGET_BASE or WIDGET_CONTROL.

Thanks for the help. I post something if that works.

Cheers,
Ben
