	Dear all,
  I installed pstricks on a Sun ULTRA 5 running Solaris 2.6 and compiled the 
test-pst.tex with no problems. I then took one particular example i.e.

\documentclass{article}
\usepackage{pstcol,pst-char}
\definecolor{lightblue}{rgb}{.68, .85, .9}
\begin{document}
\begin{figure}[h]
\begin{pspicture}(0,-1)(8.7,2.5)
  \fontfamily{ptm}\selectfont
\pscharpath[fillstyle=solid,linecolor=red,fillcolor=lightblue,linewidth=2pt]
             {\fontsize{1.5in}{1.5in}\selectfont \LaTeX}
\end{pspicture}
\end{figure}
\end{document}

and I also had no problem. When I changed it to 

\documentclass{seminar}
\usepackage{pstcol,pst-char}
\pagestyle{empty}
\definecolor{lightblue}{rgb}{.68, .85, .9}
\begin{document}
\begin{slide}
\begin{figure}[h]
\begin{pspicture}(0,-1)(8.7,2.5)
  \fontfamily{ptm}\selectfont
\pscharpath[fillstyle=solid,linecolor=red,fillcolor=lightblue,linewidth=2pt]
             {\fontsize{1.5in}{1.5in}\selectfont \LaTeX}
\end{pspicture}
\end{figure}
\end{slide}
\end{document}

I managed to compile it but, after producing the postscript file with
dvips, I got the following error from gs

Error: /undefined in tx at Dict

Is there some kind of incompatibility between seminar and pstricks? (I am
using  dvipsk 5.58f and Aladdin Ghostscript 5.50).
  Cheers,
						Bruno
