[pstricks] Bug (or feature ?) with pst-node and propser

[Christophe Jorssen]

Hello,

I am in trouble with the fellowing code :

\documentclass[pdf,draft]{prosper}

\usepackage{pst-node}

\title{}
\author{}

\SpecialCoor

\begin{document}

\overlays{2}{%
\begin{slide}{Essai}
\begin{pspicture}(-3,-3)(3,3)
  \pnode(-3,2){A1}\pnode(-.5,0){B1}
  \ncline[linestyle=dashed]{A1}{B1}
  \onlySlide{1}{%
    \ncline[linestyle=none]{A1}{B1}
    \ncput[npos=0.33]{\pnode{Temp1}}
    \psdot(Temp1)
  }
  \onlySlide{2}{%
    \ncline[linestyle=none]{A1}{B1}
    \ncput[npos=0.66]{\pnode{Temp2}}
    \psdot(Temp2)
  }
\end{pspicture}
\end{slide}
}

\end{document}

The behaviour of this is not what I expected : the _two_ nodes appear on
both overlays. I don't understand why the second node is def'ed on the first
overlay.

Is it a normal behaviour ? If it is, is there a way to make it work like I'd
like to? namely _one_ node Temp1 def'ed on overlay 1 and _one_ node def'ed
on overlay 2.

Thanks in advance

Christophe
