[NTG-context] overprinting

Hi, overprinting is broken here. I used \dostartoverprint in the past, but this no longer works. What is the recommended way for overprinted text nowadays? *EXAMPLE ATTACHED* MTXrun | current version: 2009.09.12 14:44 This is LuaTeX, Version beta-0.43.0-2009090309 pdfTeX 3.1415926-1.40.10-2.2 (Web2C 2009) Best wishes, Peter \ifnum\contextmarkmode=4 \def\dostartoverprint% yes... one of the category 'asking for trouble' :D {\ctxlua{overprints.enabled=true}} \def\dostopoverprint% {\ctxlua{overprints.enabled=false}} \fi \starttext \starttextoverprint Overprint \stoptextoverprint % fails in both marks \dostartoverprint Overprint \dostopoverprint % fails in mkiv only \stoptext
