Hi, Paul. How about changing your system date to the correct setting
so everyone's newsreaders will sort the messages properly?

  Could you please post in plain text, not HTML? Thanks.

This bug has something to do with the parsing of the color.  If you change
the definition of the cylinder's color from:
  color Blue*.7+<.3,.3,.3>
to
  color(Blue*.7+<.3,.3,.3>)
then everything works fine.  Must have something to do with the promotion
from 3d vector to 5d color.

Found and fixed.  It was a promotion problem that affected +,-,*,and /.  The
problem was when you'd do somehting like color+vector.  (vector+color would
be handled correctly).

How long before you are going to release a bug fix update ?

  I think that it's better to wait for as many bug reports as possible and
fix all of them at once than releasing an incomplete version with a few
bug fixes every two days.
