Hi Hans, Your yesterday's beta impressed me once more with the speed at which you fix the reported bugs… Thanks so much! Today I noticed something wrong with \setuparranging in mkiv, which may be due to the fact that the pagenumbering mechanisms have changed and I don't know yet the new structures: if this is the case please disregard this "bug" report. Here is a minimal example: \setuppapersize [A7][A4] \setuparranging [2*2*4,doublesided] \setuplayout [location=middle,marking=on] \setupheadertexts[Arranging pages] \starttext \startbuffer[TestPage] \strut \blank \midaligned{Is this a bug in mkiv?} \vfill \midaligned{This is page \recurselevel} \vfill \stopbuffer \showframe \dorecurse{16}{\getbuffer[TestPage]\page} \stoptext Using mkiv (ConTeXt ver: 2009.04.16 22:27 MKIV fmt: 2009.4.17 int: english/english) I get an error message: ! Undefined control sequence. \setuparranging ...gpages \abortutilitygeneration \fi \fi l.4 \setuparranging [2*2*4,doublesided] The above example works fine with mkii and the latest ConTeXt. Best regards: OK
