Hello, I know, that letting context to solve all widow/orphans automatically is possible like: \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{1}{10000} \setpenalties\clubpenalties{1}{10000} \stopsetups \setuplayout[grid=yes, setups=mypenalties] or even only: \widowpenalty=10000 \clubpenalty=10000 But this solution will let the page shorter (I will get one empty line on the bottom of the page). I would prefer to solve the widow problem manually, e.g. using \looseness=-1 or \looseness=1 on some paragraphs. In order to identify the problematic pages quickly, it would be nice to see them in the log (on the console), similarly how I see e.g. overfull hboxes. If I have an overfull line, I see: pages > flushing realpage 74, userpage 74 Overfull \hbox (2.01712pt too wide) in paragraph at lines 3504--3510 Now I would like to see a widow like: pages > flushing realpage 74, userpage 74 Underfull \vbox ... Is it something like this possible? Thanks. Pavel
