One of the possibilities is that you're always running Netscape
which redefines color palette. In 8-bit color mode (which most probably is the
one you're using) ROOT and Netscape interfere with each other. We also observe
that in this (8-bit = 256-color) mode ROOT-based graphics applications
(in our case - CDF ROOT-based event display) run much slower in the presence
of Netscape although we didn't spend much time to understand the mechanism of
this slowdown.
