I am using HP OSF/Motif on a HP 9000/800 system.  I have been using
twm for some time and does not plan to switch over to mwm that is part
of Motif.

This gives me create a couple of problems when I am writing a Motif based
application.

1) The manual specifies that  Dialogs should always be iconified
   together with the toplevel window for the application. This does
   not work when using R4 twm but (of course) when I use the Motif
   windowmanager mwm.

2) To get a modal dialog in Motif requires setting the resource
   XmNdialogStyl to XmDIALOG_APPLICATION_MODAL for the BulletinBoard
   child of the DialogShell. This works perfectly under mwm but
   not at all together with twm

Why is this so? I can think of two reasons:

- Motif is designed to always require mwm. And mwm does more than what
  is required by the ICCCM standard.

  This seems to be in direct contradiction with the whole purpose of
  X Windows and specificly the ICCCM.

- R4 twm is not compliant with ICCCM.

  I prefer not to belive in this one.


Is there anyone who can give me some hints in this area.
Thanks,
