Shut down Netscape, The Gimp, your desktop backgrounds, Gnome (if you're 
using it), and anything else that shows colour pictures, and try again.    

Your colours for X have been sucked dry.

I'm not an X programmer at all, so this might be a dumb question.  Netscape
for Un*x has the option of using a private colour map ("netscape -install",
IIRC).  With this, the colours go very psychadelic on other apps when 
netscape has the focus, and vice-versa, but netscape gets all the colours
it needs.  Is this possible under R?  If not, has anyone considered it?
It seems like yesteryear's problem, as hardware gets cheaper, but
I'm curious.

Needless to say, (1) above is the prefed option, but sometimes I have
to work on a clunky laptop with an LCD screen that's so old, it's
coal-fired.  Gives me something to wish for next fiscal year....  ;)
