Hallo Wolfgang,

...

Neither \setupwhitespace[halfline]nor \setupcolumns[blank=halfline]is working. Grid is off by default, isn't it?

Set the whitespace after \startcolumns.

This works, but shouldn't be the whitespace a global setting? I found an other ?solution? When BOTH \setupwhitespace[small] \setupcolumns[blank=halfline] is set then halfline is accepted. But halfline > small. I like context very much, but finding the right option is often a game of pure chance. Wolfgang
