Hi Marcelo,

  this problem is hardly fixable. Just as Netscape does not work if you first
would start ROOT. We could implement something like -install for ROOT but then
the screen colors would be just as bad. Best thing is to get a modern Linux PC
or "thin client" with >32K colors. Never a color problem anymore.

Cheers, Fons.
