[NTG-context] Register interaction (page references) [mkIV]

Hi, when I place an interactive register in mkIV, and then in the PDF click the pagenumber (in the index), it takes me to the wrong page; it seems to go to the absolute pdf page number(?). Example: \setupinteraction[state=start] \startsectionblockenvironment[bodypart] \setupuserpagenumber[number=1] \stopsectionblockenvironment \starttext \startfrontmatter \page[dummy] \page[dummy] \stopfrontmatter \startbodymatter \page[dummy] bla\index{bla} \stopbodymatter \placeregister[index] \stoptext Is there something new I have to configure to make it work? MkII works as expected. Thomas ConTeXt ver: 2010.05.13 12:15 MKIV fmt: 2010.5.18 int: english/english
