[NTG-context] extra width in cropbox and trimbox

Dear list, I have already reported this before (https://mailman.ntg.nl/pipermail/ntg-context/2020/099636.html). I have the following sample: \setupinteractionscreen [width=fit] \starttext \null \stoptext Mediabox is fine: [ 0 0 595.2756 841.8898 ] But cropbox and trimbox contain extra width: [ 0 0 741.4331 841.8898 ] This is caused by \setupinteractionscreen[width=fit]. Generating booklets from documents with the values above leads to wrong output. Could anyone explain me what is wrong here? Sorry, but I don’t know what I may be missing. Many thanks for your help, Pablo -- http://www.ousia.tk
