One of many examples is:

\psset{xunit=.5cm,yunit=.5cm,curvature=1 .1 .75,plotpoints=200}

In the first edition I used \pspolygon without hatchangle and the result
was hlines at 0 degree and vlines at 135 degree (assuming 0 degree as
the origin with counterclockwise direction). With PST97 the hlines
appeared at 90 degree and vlines at 45 degree; so I had to add a
hatchangle of 90 degree to compensate for this behavior.
I'm using the Y&Y DVIPSONE driver with appropriate header files to work
with PSTricks (maybe the problem is here!). These are PSTRICKS.CON 799
26.07.97 20:20 and PSTRICKS.PRO 12.339 08.09.97 18:36.

Oh God! Sorry. Maybe it was to logical for me to have Bc and cr for
alignment at the ticks!

It's enough for me but not for my publisher!
