Great news. So be it in 3.7a98pl421 :-)

Yes. Just now (on pl338 still with the eps enhanced terminal) and I get
translucent symbols: 

  70 +
  71 x
  72 *
  73 hollow box
  74 black filled box
  75 hollow circle

No clue why this is happening.

What ever you do, you have my blessing :-)

By the way, another one ... could the colours of the key _text_ be set
to black again (optionally perhaps)?  When using the colour postscript
terminal one can get great plots, and I am glad the key lines / points
are in the same colours as the data, but the key description, I'd rather
have in black like the rest of the figure labelling.

Any ideas or opinions?


  Cheers!  Stefan
