Hi Marcin, I tested your file and noticed the issue you are reporting. In your case you can use \startsimplecolumns to get rid of the page break (however there is a small problem with the distance between the text and the items):
\startchapter[title={Nim-suma liczb całkowitych nieujemnych}] \startexercises \startitem Przelicz następujące liczby w~zapisie dwójkowym na system dziesiątkowy: \startsimplecolumns \startitemize[r][left=(,right=),stopper={}] \startitem \math{(101)_2} \stopitem \startitem \math{(101011)_2} \stopitem \stopitemize \stopsimplecolumns \stopitem \startitem Przelicz następujące liczby na system dwójkowy: \startsimplecolumns \startitemize[r][left=(,right=),stopper={}] \startitem \math{10} \stopitem \startitem \math{77} \stopitem \stopitemize \stopsimplecolumns \stopitem \stopexercises \stopchapter Best regards: OK On 30 juin 2012, at 00:16, Marcin Borkowski wrote: > Dnia 2012-06-29, o godz. 23:30:13 > Marcin Borkowski <mb...@wmi.amu.edu.pl> napisał(a): > >> Hello, >> >> I encountered a weird problem with >> >> \startitemize[columns] >> >> Namely, sometimes ConTeXt (MkIV) puts a pagebreak before the >> itemization.
