[pstricks] psPolynomial

[McGarry Vince]

Does anyone else see two distinct lines here?

\documentclass{minimal}
\listfiles
\usepackage{pst-func}

\begin{document}
\begin{pspicture*}(-5,-5) (5,5)
\psaxes(0,0)(-5,-5)(5,5)
\psplot{-5}{5}{-1 -2 x mul add}
\psdots(-2,3)(1,-3)
\psPolynomial[coeff=-1 -2]{-5}{5}
\psdots(-2,3)(1,-3) % not at the same location as the previous call  
to psdots.
\end{pspicture*}
\end{document}

The problem appears to be with psPolynomial which then affects later  
drawing.
