[NTG-context] footnotes on wrong page

What is the setting that forces ConTeXt to keep footnotes on the page where they are called? In the following example, \setupinteraction[state=start] \setupnotation[footnote][interaction=yes,way=bytext] \setupnotation[footnote][split=verystrict] \starttext \dorecurse{50}{some text\footnote{a footnote} } \stoptext the call for note 42 and the note itself are on different pages. I realize that this may be an extreme case, but, regrettably, that is what I have in a review that I am typesetting. Alan
