Good morning. One reason for me to switch to ConTeXt were its macros for typesetting in columns that are highly superior to any such macro I have ever seen. (I typeset almost all my documnts in two columns.) But I am not able to supress one strange feature: some pages are one more line longer than they should be. It happen randomly -- or at least I was not able to find out when it happens. Therefore I'm not able to prepare an minimal file. I thougth that setting \widowpenalty=0 \clubpenalty=0 \brokenpenalty=0 \normalbottom may help, but it does not. Can you tell me how to fix this very problem? Well, it does so on all versions of ConTeXt I have ever tried and both with teTeX and TeXLive distribution. Many thanks for your attention and help. Yours Michal Kvasnicka P.S. my document setting is like this (some example can be found at http://www.econ.muni.cz/~qasar/tmp/delba_prace.pdf): % output=pdf \setupbodyfont[ss,10pt] \setuplayout [topspace=2cm, height=fit, lines=55, backspace=15mm, width=fit, margin=0pt, header=3\baselineskip, footer=0pt, grid=yes] \setuppagenumbering[location=] \setupheader[style={\em}] \setupheadertexts[Axel Leijonhufvud: Jednotlivec, trh a průmyslová dělba práce][pagenumber] \setupindenting[medium] \indenting[first] \setupfootnotes [location=columns, rule=off, before={\blank[3*line,small]}, after=] \setupfootnotedefinition [location=left,width=fit, sample={\mathematics{\star\star\star}\ },hang=1] \setupcolumns[balance=no] \widowpenalty=0 \clubpenalty=0 \brokenpenalty=0 \setuphead[section] [number=no, style={\bf}, before={\blank[3*line]}, after={\blank[line]}, indentnext=yes]
