between the <pre>-tags I do have HTML-coding.
I had
* loosing text after the new section
* doubling of sections
* complete corruption
I've noticed that using the <pre> tag does sometimes cause the paragraph
after the </pre> to disappear. Switching to <nowiki> seems to fix the
problem, but you then need to escape any code by hand, e.g. using >
as Tels suggested.
Cheers,
Adam.
