Dear list, I have the following sample: \setupinteraction[state=start] \placebookmarks[chapter] \startsectionblockenvironment[bodypart] \writebetweenlist[chapter]{{\blank[3*halfline]}} \stopsectionblockenvironment \startsectionblockenvironment[backpart] \writebetweenlist[chapter]{{\blank[3*halfline]}} \stopsectionblockenvironment \starttext \chapter{Introduction} \startbodymatter \chapter{First Chapter} \stopbodymatter \startbackmatter \chapter{Conclusions} \stopbackmatter \stoptext For some strange reason, the \writebetweenlist commands also add bookmarks with a question mark to the PDF bookmarks in the PDF file. Is this a bug or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk
