Yes.  Set the window's bit-gravity to ForgetGravity.  Since this is the
default, something somewhere along the line (Xt or the widget set, most
likely) is changing it.  I suppose you could just bash the bit-gravity
of your window, but there's no guarantee that whatever changed it for
you in the first place won't helpfully change it back, so you should
get out the documentation and find out how to suppress this behavior.
(I can't help you there; I don't know Xt or widgets.)
