  Updating today one of my documents including various PSTricks diagrams,
I found that there is a bug in \nccircle with PST97.

  Reason is that the PostScript code is from pst-beta.bug from 0.93 version
but the TeX code itself is a little bit more recent - and incompatible.

  Test case is:

\documentclass{article}

\usepackage{pst-node}

\begin{document}

\rnode{A}{X}
\nccircle{A}{1cm}

\end{document}

  Correction I found is to make the following changes in dvips/pst-node.pro

% Version 0.93a/b-97 patch 1, 97/05/09.

% DG/SR modification begin - 9 May 1997

mul add dup 5 1 roll 90 sub PtoC 3 -1 roll add /Y ED add /X ED /NAngle ED
% DG/SR modification end

  This will be propagated soon in CTAN file.
