    You must tell us more about your environment...

    In Xt release X11R3 and Motif 1.0, the colormap resource is mostly
    ignored ....

    The second part - colormap ONLY installed when the widget has FOCUS
    is a part of the WINDOW MANAGER colormap focus policy, which is very
    often identical to keyboard focus policy. I have (yet) to see a system
    that will be able to use multiple colormaps at the same time. Most
    current system can only use one colormap - and which one is used is
    decided by the window manager, which is in charge of colormap installation.

    Note however, that the WM colormap handling also uses the WM_COLORMAP_
    _WINDOWS property (at least there are WM's which do and which do NOT...).
