[NTG-context] line break between number and footnote text in paragraph footnotes

Hello, I have a problem with paragraph footnotes. I don't know how to prevent a line break occurring between the footnote number and the footnote text. Sometimes a thing like this happens: ... [main text] ... -------------- 1. text of the first footnote --- 2. text of the second one --- 3. text of the third one Is there a way to force ConTeXt to keep the "3." with "text of the third one"? Thanks in advance, Massi
