(Untested) Did you try:
\startitemize[intro]
AFAIU, intro prevents a page break before itemize.

IIRC, it also makes float placements harder to predict. Best wishes, Taco ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

Too bad. I think, there can be still some enhancements: in LaTeX, there
is never a page break after a section header, but with ConTeXt there is
sometimes by surprise...

No more page break after the section head, but that's normal: you changed
the number of lines.
