Well, after some trial and errors, I think I get what is going on with the highlight. When on the generated pdf the </highlight> is at the edge of the paper, the space is eaten. Hacky workaround follows: %% start example \setupbackend[export=yes] \definehighlight[emph][style=italic] \startmode[huge] \definepapersize[huge][width=4000mm] \setuppapersize[huge][huge] \setupbodyfont[8pt] \stopmode \starttext \startparagraph Published on \dontleavehmode\emph{Dissonanze} vol. I \stopparagraph \startparagraph Published on vol. I Published on vol. I Published on vol. I Published on \dontleavehmode\emph{Dissonanze} vol. I \stopparagraph \startparagraph Published on vol. I Published on vol. I Published on vol. I Published on blablabla \dontleavehmode\emph{Dissonanze} vol. I \stopparagraph \stoptext %%% stop example Compiled with context prova.tex, the space is eaten on the second paragraph. See produced pdf. <?xml version='1.0' encoding='UTF-8' standalone='yes' ?> <!-- input filename : prova --> <!-- processing date : Mon Nov 7 17:43:10 2011 --> <!-- context version : 2011.11.04 14:15 --> <!-- exporter version : 0.30 --> <document language="en" file="prova" date="Mon Nov 7 17:43:10 2011" context="2011.11.04 14:15" version="0.30" xmlns:m="http://www.w3.org/1998/Math/MathML"> <paragraph>Published on <highlight detail="emph">Dissonanze</highlight> vol.

I</paragraph> </document> With `context --mode=huge prova.tex` everything is fine (As the paper is 4 meters long on 8pt!) <?xml version='1.0' encoding='UTF-8' standalone='yes' ?> <!-- input filename : prova --> <!-- processing date : Mon Nov 7 17:44:02 2011 --> <!-- context version : 2011.11.04 14:15 --> <!-- exporter version : 0.30 --> <document language="en" file="prova" date="Mon Nov 7 17:44:02 2011" context="2011.11.04 14:15" version="0.30" xmlns:m="http://www.w3.org/1998/Math/MathML"> <paragraph>Published on <highlight detail="emph">Dissonanze</highlight> vol.

(Even if, speaking about impression, I believe the 4 meters are enough for the average usage). Best wishes -- Marco
