Hello all, The following example produces two log entries that seem a bit odd. The log entries are: backend > bookmarks > confusing level change at level 3 around '1 body1' backend > bookmarks > confusing level change at level 3 around 'back1' and they refer to the first chapter of the bodymatter and the first chapter of the backmatter, respectively. The example: \setupinteraction [state=start] \placebookmarks [chapter] \starttext \startfrontmatter \startchapter [title=front1] \samplefile {knuth-gpt} \stopchapter \stopfrontmatter \startbodymatter \startchapter [title=body1] \samplefile {knuth-gpt} \stopchapter \stopbodymatter \startbackmatter \startchapter [title=back1] \samplefile {knuth-gpt} \stopchapter \stopbackmatter \stoptext Does the level change message suggest that something is missing in the document? -- Rik
