Hi, the following test file has a weird page break, caused by a too wide image set with \definecolumnsethsize. I am talking about the blank space at the right of the image. \definecolumnsethsize defines a with of 202.01262pt, that's too wide, 202pt would be correct, I guess. Is that a rounding error? If the figure width is slightly decreased (see the commented part), the first page looks as intended. But that's exactly what the command \definecolumnsethsize is for -- to get the correct size. Another workaround is to define the column width, so it is a know value. The behaviour is reproducible in all betas. Bug or not? \useMPlibrary [dum] \definecolumnset [MyColumns] [distance=8mm] \starttext \startcolumnset [MyColumns] \definecolumnsethsize{MyColumns}{1}{1}\ColumnWidth \input knuth \startplacefigure \externalfigure [dummy] [width=\ColumnWidth, height=9.5cm] %\externalfigure [dummy] %[width=\dimexpr\ColumnWidth-1pt\relax, height=9.5cm] \stopplacefigure \dorecurse{4}{\input knuth} \stopcolumnset \stoptext Marco
