This minimal example: \starttext \currentdate-\currenttime\quad\ConTeXt-version=\contextversion\blank Testing \ConTeXt macro\ \tex{inmargin} \blank Some text to fill the body of the text.\par \inmargin{\hbox{abc}} Some text to fill the body of the text\par \stoptext produces an underfull hbox: Underfull \hbox (badness 1210) in paragraph at lines 6--6 [][][] the same happens with the line: \inmargin{abc} Underfull \hbox (badness 1210) in paragraph at lines 6--6 []<9: lmroman12-bold @ 12.0pt> abc[] addition of \hfil or \hss doesn’t help. My conclusion: this is somewhere located in \inmargin. It would be nice if this can be resolved, because in procession some 500 \inmargin’s the log is cluttered with all these messages. dr.
