Hi all, I encountered a very strange problem. I want to have section headlines expanding the whole textarea, but the following copy text of the section shall be typeset in columns. I have this setup and it works fine. \setuphead [section] [ insidesection=\startcolumns, aftersection=\stopcolumns, ] Except for one big problem. ConTeXt (current lmtx from 2020.05.18 16:50) sometimes has problems to make a page break. And I get the weird result shown on the attached screenshot. After the page break the text of the section does not continue. Instead a number is shown. In the log file I can't find something suspicious. When I compile the source with current context (2020.01.30 14:13) I get something like an infinite loop. ConTeXt hangs and has to be killed with kill pid, Ctrl-C in terminal does not work So, in my opinion my layout or setup causes a bad situation, where ConTeXt does not know where to make a page break. While context hangs and warns me, lmtx runs smoothly but places a number in the text, which is bad as I might overlook it. I tried to make mwe but I cannot reproduce the error. Any ideas to improve my setup? Is this a bug or the intended behaviour? juh
