Apparently it's a feature.  So, how do you circumvent it?

Answer #1
  Two different folks at sun (David Berry (dtb@Eng.sun.com) and Larry
  Wake (Larry.Wake@West.Sun.COM)) provided a simple answer.  Just set
  the button's PANEL_NOTIFY_STATUS to XV_ERROR before returning from
  the notify procedure, and the command frame will be left up.  I.E.
  (pasted right out of Larry Wake's note):

  void
  some_button_notify(item, event)
  Panel_item      item;
  Event           *event;
  {
      [... your code here ...]
      xv_set(item, PANEL_NOTIFY_STATUS, XV_ERROR, NULL);
  }

  This is what I'm using now.

Answer #2
  Force the push-pin in when you make the command frame.  (Marc Ramsey
  (autodesk!sunra!marc@fernwood.mpk.ca.us) and Frame Hage
  (fhage@brainiac.rap.ucar.edu))

Larry Wake also pointed out that it IS indeed in the XVPM - bottom of
page 148 and top of page 149.  I had read that chapter, but missed
that little tidbit completely...

Thanks to all who replied.  I wasn't expecting such a fast response.
I got a working answer within an hour of my post...  And to think some
consider reading news a waste of time.

Take care,
