I'd made the mistake of using the XA_WINDOW atom, rather than interning an atom
for the widget.

f.restart doesn't seem to work every time. Quiting mwm and restarting seems to.

I made a quick test with twm, and that never seems to install the
colormap at all.
Anyone know of similar problems with other (supposedly ICCCM) compliant
window managers.

P.S. Thanks for the help (once again!!!).
