hi,
grid compiles with pd-0.35test n > 4
in fact, you have 2 options :
a/ either use pd-0.35test n > 4 as Christian suggested it.
b/ either replace :
te_xpix --> te_xpos
and
te_ypix --> te_ypos
if you don't want to change your pd release.
this applies to _ALL_ graphical externs, unfortunately.
cheers,
Yves/
