Hello, looking for the multicolums of fixed height I've found the solution from Wolfgang [1], which doesn't work with latest beta (mkiv): \usemodule[streams] \definestreamlayer[test][method=overlay] \setupbackgrounds[page][background=test] \starttext \startstreamlayer[test] \startcolumns \input knuth \stopcolumns \stopstreamlayer \setlayer[test][x=5cm,y=10cm]{\placestreamlayer[test]} \stoptext Here is the scenario: tree columns of fixed height should be placed at the precise place (end of the page, so they can also float there). It is necessary to measure their natural height, also, to check if all the material fits in the the specified height or find some other way to check if the material is lost or not. Do you have any hints? Thanks, Jano [1] http://thread.gmane.org/gmane.comp.tex.context/55324/focus=55433
