I'm somewhat of a novice at x-window programming and am looking for some help
in installing a grayscale colormap.  I was able to do this successfully on
one configuration, but am having trouble on a second configuration.  

I create a colormap with a visual of depth = 8.  However, I am unable to
XStoreColor all 256 color cells.  On one configuration I can, on the other
I cannot.  If the depth =8 on both, what is the difference?  It looks like
I am not able to set 32 of the colors. 

I originally tried to use a standard grayscale colormap, but the
XGetStandardColormap call fails.

Any help would be appreciated.
