Re: sections

[Pablo Rodriguez <oinos@gmx.es>]

Hi Hans,

I found out that the issue I wrote about in my previous message is about
widow and orphan lines.

Here is the sample:

    \showframe\showgrid
    \setuplayout[setups=*lessstrict]
    \startsetups[*lessstrict]
        \setup[reset]
        \widowpenalty=10000
        \clubpenalty=10000
    \stopsetups
    \setupbodyfont[pagella,15pt]
    \starttext
    \chapter{Chapter}
    \section{Section}
    \dorecurse{103}{\ConTeXt\ is fun! }

    \subsection{Subsection}

    \ConTeXt\ is fun!
    \stoptext

Many thanks for your excellent work,

Pablo
