Oh, sorry, Dominik. Did you think I meant *your*
programming error!? No indeed. I think there is
an error in XPalette. :-)

I've done a quick look and it seems to me the problem
is in the internal routine COLOR_CONVERT, although I
can't imagine why this should be so. But I stand by
my earlier theory that the problem is some assumption
about the state of system variables. I think you need
to ask RSI for help in this case.

Cheers,

David
