It sounds like you are calling XtMakeGeometryRequest from the
application.  If so, this is a no-no; XtMakeGeometryRequest is
intended to be called by the widget whose geometry is being
changed, not by a third party.  You get this message presumably
because you specified a ShellWidget in the call and, in R3,
Shells have no parent to field the request.  If you're realy
only changing stacking order then you'll be able to get away
with this in R4, but it's still not recommended practice.

Xt does not have any special support for third-party stacking
changes; in this case, you should simply make direct Xlib
calls (e.g. to XRaiseWindow) on the Shell window.
