Hi, nice surprise, with the latest beta my document just grew 15 pages ;) On a closer look, it turned out that the numbering of my body part is not reset to 1, instead it continues with the next number after my frontpart. Here is how I did set this up long time ago: \startsectionblockenvironment[frontpart] \setupheader [before={\ss\switchtobodyfont[10pt]}] \setupheadertexts [section][pagenumber][pagenumber][chapter] \setuppagenumbering [alternative=doublesided, partnumber=no, location=, style={\ss\bold}] \setupuserpagenumber[numberconversion=romannumerals] \stopsectionblockenvironment \startsectionblockenvironment[bodypart] \setupheader [before={\ss\switchtobodyfont[10pt]}] \setupheadertexts [section][pagenumber][pagenumber][chapter] \setuppagenumbering [alternative=doublesided, partnumber=no, location=, style={\ss\bold}] \setuppagenumber[number=1] \stopsectionblockenvironment \startsectionblockenvironment[backpart] \setupheader [before={\ss\switchtobodyfont[10pt]}] \setupheadertexts [chapter][pagenumber][pagenumber][chapter] \setuppagenumbering [alternative=doublesided, partnumber=no, location=, style={\ss\bold}] \setupuserpagenumber[numberconversion=numbers] \stopsectionblockenvironment \startsectionblockenvironment[appendix] \setupheader [before={\ss\switchtobodyfont[10pt]}] \setupheadertexts [section][pagenumber][pagenumber][chapter] \setuppagenumbering [alternative=doublesided, partnumber=no, location=, style={\ss\bold}] \setupuserpagenumber[numberconversion=numbers] \stopsectionblockenvironment Any ideas or suggestions? Thanks in advance! Steffen
