[pstricks] Problem with miktex2.5

[azzam.hassan at voila.fr]

 Hi all Pstrickers
After updating miktex to miktex 2.5 version I remarked that the algebraic option does not work when visualisin the ps file using ghostview

below the tex code :
\documentclass[fleqn]{article}
%
\usepackage{pstricks,pstricks-add}
%**************************
\begin{document}%
 \begin{pspicture*}(-2,-2)(2,2)
 \psaxes(0,0)(-2,-2)(2,2)
 \psplot[algebraic=true]{-2}{2}{x*2-1}
 \end{pspicture*}
\end{document}


The code works perfectly when using the rpn notation
