#23 Problems with PSTricks and Prosper together

[Anonymous]

Hi,
I seek help to get PStricks to work in Prosper, as I
manage to get it working in a "normal" Latex class, but
not for prosper. In the normal file it works as I
expect according to manual and dimensions are correct.
In prosper the following is problem:
1: It gives unknown command on many \ps* commands in
prosper.
2: I have severe problems to translate away from the
current point in a
predictable manner.
3: The scaling is wrong, both using default 1cm unit
and also using the
\psset{unit=1cm} which seems having no effect in
prosper.

I hope someone can help me to solve this so I can make
full use of the very nice prosper. Thanks in advance.

kind regards,
