[NTG-context] Problem with \columnsetspan

Hello, I tried columnsets today, and the following minimal example shows that something is wrong with columnsetspans (which I wanted to use to make a title). \definecolumnset[main][n=2] \definecolumnsetspan[title][n=2] \starttext \startcolumnset[main] \startcolumnsetspan[title] \input knuth \stopcolumnsetspan \dorecurse{10}{\input knuth} \stopcolumnset \stoptext Is it a bug or am I doing something wrong? BTW: is there a better way to have a title centered on the top of the page and then text in columnsets? Regards, -- Marcin Borkowski http://mbork.pl
