Hello, because of problems with a double-sided document, I compared ConTeXt behaviour in TeXlive2010, TeXlive2011 and beta-version at contextgarden.net. I found out, unfortunately, that the following code works differently: only on TeXlive2010 version I received the proper design, i.e. even page has mark on the left, odd one on the right, while the TeXlive2011 and the beta produce single-sided layout, i.e. marks are on the right side in all pages. Or is there any special option in the current version? Thanks for a help, Tomas Hala \starttext \setuppagenumbering[alternative=doublesided] \setuplayout[location=doublesided,marking=on] \setuppapersize[A5][A4] blablablabla \page blablablabla \page blablablabla etc. \stoptext
