  DECwindows colormap full? (VCB02) 
 The Question is:
 
I recently purchased and installed DECwindows Motif on a VAXstation 3900.
The install went great, and it passes the IVP test.  However when I go to
change the window colors, I get a Problem report back stating "Your colormap
is full.  You may not be able
 to perform all color setup options."  What can I do to correct this?
Incidentally, the graphics hardware is a 4-plane GPX system.
 
 
 The Answer is:
 
  The OpenVMS Wizard is unaware of a VAXstation 3900 configuration,
  and will assume this is a MicroVAX 3900 with a VCB02 (QDSS) Q-bus
  graphics controller installed.
 
  A colormap is considered "full" when all of its entries for colors
  have been allocated by applications.
 
  Various DECwindows tools can require enough colors (16 or more) to
  fill four planes -- the colormap widget will then consume the colors
  that remain.  (The changes can usually be made, but you'll have to
  log out and back in to see the changes.)
 
  You will likely want to upgrade to an eight-plane VCB02 configuration,
  adding an additional 4-plane board (a second M7168) to the existing
  two-board (M7169 and M7168) VCB02 configuration.
