[NTG-context] Double interline spacing with headings

Hi list, I want to have double line spacing in my document setup, including the headings. But in the following example, the space before the heading is slightly different from the interline spacing between the other lines. How to do this right? (standalone MkIV 2011.09.20 00:09) \setuphead[section][style=normal, interlinespace=big, before=, after=] \starttext \setupinterlinespace[big] \input ward \section{\input ward} \input ward \stoptext TIA for your help! Kind regards, Stefan
