I was bitten by the mapcolor bug today on a 4D-240 GTX.  It was in a 
routine which set a lot of colors in a tight loop.  For the first time, I 
compiled it with -O2.  This speeded up the loop just enough so that the 
mapcolor sometimes failed.

I put in a tiny delay, and everything worked fine.

If you are getting unexpected colors in color map mode, check to see if 
you are calling mapcolor too fast.
