Thats very good of you.

X pixmap in memory and hand that to the Motif drawing widget. That way, all the
expose events were handled by the toolkit rather than by myself ... or am I getting
mixed up with the original version on the Archimedes ?
The range of toolkits available these days is truly bewildering.

Unfortunately all my computer related activities will be suspended for two weeks from
Thursday so I can't even look at the toolkits.
