Maybe the X server under cygwin or RH does not by default create the
visual expected by the application. Did you compare the output of
xdpyinfo between Exceed and RH?

ITIYM 'the Motif window manager'. That indeed is not a problem with
Exceed, which *does* honor the WM properties used by the Motif shell
widgets, and *is* likely to be a problem with RH, at least when using
KDE, because the KDW window manager does not honor some of these
properties. Eg a window supposed to be fixed-size with MWM will have
effective resize handles with KDM. I have not yet found a way to deal
with that specific issue even for applications of which I do have the
source code! One problem has been that I have not yet found any Xt-based
application that *is* non-resizeable under KDE. Ideas, anyone?

I have not yet tried our Motif apps under a recent Cygwin so I cant say
anything about cygwin.

In view of the previous paragraph, could you clarify the question?
