Hello, I took me quite some time to extract the following sequence from a 300p book, that makes the compilation hang. It looks like if it's in an infinite loop, but I don't know what happens. It seems related to the interaction of float, verbatim, and background stuff. I thought it was a local resource problem (few memory on my machine) but trying the code in live context never gave something either (i hope it is not still running!). What's wrong in my definitions/setups to have such a behaviour? \setuplayout[middle] \setupcolors[state=start] \setupinteraction[state=start] \definefloat[dbsidebar] \setupfloat [dbsidebar] [criterium=0.7\textwidth, leftmargindistance=-\outercombitotal, rightmargindistance=-\outercombitotal, default={outer,middle}] \setupcaption[dbsidebar][location=bottom,number=no] \defineframedtext [framesidebar] [width=.9\textwidth,bodyfont=small, corner=round,background=screen,backgroundscreen=.95] \setupbackground [background=screen, frame=on, strut=yes, topoffset=2mm, width=broad, before=\blank, after={\blank[small]}, align=right] % Verbatim environment for programlisting \definetyping[code] \setuptyping[code] [bodyfont=small, before={\startbackground}, after={\stopbackground}] \starttext \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \stoptext Regards, BG
