I think you should track the pressed/released buttons from here and not
change them in the motion callback.

have you looked into moveTo and why it does not do anything, i.e. does
it return early because of a check at the beginning that is not
satisfied? What are the values passed into it, do they make sense and
match your mouse movement?
I don't see much of a difference between your code and what the SSM
uses, so this is a bit puzzling. I assume you already made sure your
callbacks are called, i.e. especially the motion() one gets called all
the time when the mouse moves?

hm, that setup does not sound overly exotic and there is nothing that
prevents the SSM from being used in a cluster (the cluster examples use
it). Have you tried to just have the SSM manage the client window and
perhaps instead of calling ssm->redraw() call ssm->update() and
clusterWin->render() to get the cluster and client windows to render?

Carsten
