Hi,
I'm re-posting my previous reply to a request from Wolfgang Schuster to supply
an example that exhibits the problem of headers at page bottom. In my previous
reply the attached example was more or less obscurely hidden in a link at the
bottom of the Digest.
This time I included the example in the e-mail -- it's a bit long I'm afraid.
Here's an example of a ConTeXt file where a header occurs at page bottom.
The subsection named "Perl snippet" occurs at the bottom of page 2, followed
by framed text on page 3. It would be much nicer if the header would be
written on page 3. Note: I extracted this example from a real-life text; for some reason
the frames in the example are drawn wrongly, but this is beside the point.
Run the example with texexec --pdf test.tex
These are the outputs of pdfetex --version and texexec --version on my system (Fedora Core 6):
texexec : TeXExec 5.2.4 - ConTeXt / PRAGMA ADE 1997-2005
texutil : TeXUtil 9.0.0 - ConTeXt / PRAGMA ADE 1992-2004
