Hi,

looking for a reliable soluion to the problem of keeping section heads  
with following paragraphs I found the email below from Hans 2003.

But using it gives an error (see below):

\starttext

\definehead[myhead][section]
\setuphead[myhead][after={\blank[big]\blank[inhibit]}]

\input tufte \par
\input knuth \par
\input tufte \par
\input knuth \par

\myhead{Sektion}

\index{Index}

\subsection{Subsektion}

\input knuth \par

\stoptext

Is "inhibit" broken?
