[pstricks] parameter dotted

[Denis Vergès]

Hello,

Since I work with TeXShop (Mac OS X 3.9) the parameter « dotted » don't 
work.
For instance :


\psset{unit=2cm}
\begin{pspicture}(-3,0)(3,4)
\psaxes{->}(0,0)(-3,0)(3,4)
\uput[d](3,0){$x$} \uput[l](0,4){$y$}
\psplot[linestyle=dashed]{-2.835}{3}{1 2.71828 x neg exp sub x 1.41421 
mul div}
\psplot[linestyle=dotted]{-2.33}{3}{1 2.71828 x neg  exp sub x div}
\psline[linecolor=blue](-3,2.124)(2.125,0)
\end{pspicture}

The second curve is not drawn.

Thanks for your answer.
