Hans, here is what I tried (MWE):

\setuppapersize[A4]

\starttext

\section{Introduction}

\startmixedcolumns[distance=5mm, balance=yes]

\dorecurse {25} {

\subsection{Subsection Heading}

\penalty10000

If I had not participated fully in all these activities, literally
hundreds of improvements would never have been made, because I would
never have thought of them or perceived their importance. \endgraf

}

\stopmixedcolumns

\stoptext


As you see, I tried \penalty10000 after the subsection heading.
But in the resulting PDF, on page 3, in the left column, we see a
subsection heading at the bottom of the column with nothing below it. So
something didn't work.

Am I not doing it the way you meant?


Thanks for your help,
Lars
