Hello, There's a strange behaviour with comments when using \startcomment...\stopcomment. In some cases the comments are skipped. The comment always appears with \comment{...}. Here is a summary of the tests I've done: Case OK: comment starting a paragraph Case KO: comment at the end of a single paragraph Case OK: another paragraph follows the comment Case KO: the comment is within a single paragraph Case NOK: the comment appears (not in the last paragraph), but not in the middle of the paragraph, but at the end. Case OK: comment starting a paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case KO: comment at the end of a single paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \stoptext Case OK: another paragraph follows the comment \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case KO: the comment is within a single paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case NOK: the comment appears, but not in the middle of the paragraph, but at the end \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \input tufte \stoptext Regards, BG
