Dunno why, but you could always do somthing like......

	current_window = winget();   /* Remember what the current window is */

	noport();                    /* Open a window that never appears */
	color_window = winopen( NULL);

	Read the color map here.

	winclose( color_window );

	if ( current_window > 0 )  /* >= ????   I forget.... */
		winset( current_window );

Yuk, what a kludge.
