Hello,

has anybody encountered a similar problem with node connections and
overlays, or can somebody help me:

I try to make overlay slides with node A on the first slide, node B on 
the second and an edge between node A and node B on the second slide,
too. 

The problem is that the edge does not connect nodes A and B but
goes out of the respectivve slide. I imagine it tries to connect to the other
slide where node A (node B, resp.) is located. 

I tried it with the following simple lines:


\documentclass[a4,12pt]{seminar}

\usepackage{pst-tree}

\usepackage{semcolor}
\usepackage{semlayer}
\input{seminar.bug}

\begin{document}


\begin{slide}
\pstree{\Toval[name=A]{node A}}{}

\begin{overlay}{1}
\pstree{\Toval[name=B]{node B}}{}
\ncarc{->}{A}{B}

\end{overlay}
\end{slide}

\end{document}

Can anybody help me?

Yours, Holger
