All of the above is telling you that there are not enough colors available
when McIDAS starts up.  What you need to do is insure that McIDAS starts
first so that there are enough colors available.  The most typical situation
that causes the lack of colors is Netscape (tm) already running.  Also,
if you are using the new Gnome stuff in RedHat 6.0, you are probably using
up most of the colors with it.  In this instance, you will need to investigate
how to cut down on the number of colors that it uses so that more are
available for McIDAS.
