Minimal code: \definecolumnset[columntest][n=2,balance=yes] \definecolumnsetspan[wide][n=2] \starttext \startcolumnset[columntest] \startcolumnsetspan[wide] \dorecurse{3}{\input knuth\par} \stopcolumnsetspan \dorecurse{10}{\input knuth\par} \stopcolumnset \stoptext There is no columnsetspan, and a wide frame shows up instead. -- Best Regards Chen
