Hi!
      I have been trying to get colourmaps to work on our Apollos for
a little while now but with marginal success. I was under the impression
that in X if a window became in focus that the colourmap for that window
would be used for the screen. I am writing an image processing package
and I have made a gray scale colourmap and set the colourmap resource of
my root widget (Motif) to my colourmap. I retrieve the colourmap resource
from one of its childeren and the my colourmap was successfully
inherited. However my colormap is not installed when one of my windows
become in focus. If I attach my colourmap to the Root Window any windows
that are realized after I have set my colourmap inherit my colormap and
it is installed when these windows become in focus.
      I didn't think that there should be any difference if my colourmap
was inherited from the root window or from my root widget.

      I would appreciate any suggestions!

                  bye,
                        Glenn
