    WoKo> legend(1,9,letters[1:5],pch=1:5)
    WoKo> dev.off()

    WoKo> The result looks quite different compared to the X-windows

    WoKo> Is it a bug?
yes, definitely.
there's a second (less severe) bug, too :

The second symbol (triangle)
is \Delta /\  on x11 (and postscript in R <= 0.65)
          --    __
but is \Lambda  \/  for postscript in R 0.90.0..

    WoKo> How can I work it around?

as you said: by not using  pch=1.... :-)
a patch will probably appear "soon"...
