Updated to Feb. 8 beta, now none of my documents with columnsets will compile. Without the columnset, the example below works fine: \definecolumnset[body][n=2] \starttext \startcolumnset[body] \input tufte\par \stopcolumnset \stoptext Error message: 1 \definecolumnset[body][n=2] 2 \starttext 3 \startcolumnset[body] 4 >> \input tufte\par 5 \stopcolumnset 6 \stoptext \154>columnset:page_otr_command_routine ...outine \page_otr_commands_process ...outineparameter {#1} }\ifx \page_otr_specifics_... <inserted text> ...cess {page_otr_command_routine} \page_otr_commands_process... <inserted text> ...eset \the \t_page_otr_commands \let \page_otr_commands_pr... \setup_outputroutine ...\everyswitchoutputroutine \fi \else \let \previousou... <to be read again> \doifelsenothing ... l.4 \input tufte\par ? -- Peter Park Nelson peter.park.nelson@gmail.com
