Dear all,

In some text I am typesetting I noticed that the text following a section was always starting on same page (which is all fine), but in some cases the text preceding the section heading was also finishing on same page, ie the last paragraph before the section heading was broken in previous page, say N lines on previous page and 2 in the page in which the section starts (I have \widowpenalty10000 that’s probably why there are 2 lines in new page), even if there is space in the previous page for the 2 lines (there are even 3 blank lines at the end of the page).

Apparently I could solve this “problem”, adding some 0 penalty:

\definevspacing[BeforeHeading][penalty:0]

\def\BeforeBook{\blank[BeforeHeading, line]} % was \def\BeforeBook{\blank[line]} which seems to avoid breaking page between text before heading and heading itself

\setuphead[section][before=\BeforeBook]

My question is simply, is that a correct way to fix the problem, or is that just “luck” this fixes the issue ?

Thanks a lot,

Best regards

Joseph Canedo
