[pstricks] pst-circ bug or bad configuration?

[Joel Salomon]

When I try to typeset the following file:

\documentclass{article}
\usepackage{pst-circ}
\begin{document}

\begin{pspicture}0,0)(8,6)
\psgrid[subgriddiv=1,griddots=10]
% Node definitions
\pnode(0,1){A}
\pnode(3,1){B}
\resistor (A)(B){$R_1$}
\end{pspicture}

\end{document}

I get the R_1 in the lower-left corner of the pspicture. If I have
more than one element, *all* their labels are superimposed on the same
spot.

Am I doing something wrong? Have I configured something wrong in my
teX distro (I'm using MikTeX for Windows, in case it matters)?

Thanks for the help,
