Hello, I'm using: current version: 2012.02.08 21:58 but this problem happens in more versions. See example document: http://bruxy.regnet.cz/tmp/twocols_fight.pdf http://bruxy.regnet.cz/tmp/twocols_fight.ctex After 4th chapter, there is unwanted blank page. The blank page appears every time, when the chapter is on the top of page. I want to prepare two columns layout, but chapters should be overlaid over two cols. I played also with \definecolumns and columnset environment, but columns were not balanced and doesn't work as I expected.
