Hans, I think there is a bug in your s-pre-60.tex module regarding the step
mechanism interacting with section blocks: the head titles disappear each
time ConTeXt starts a new section block. I have found a way to solve this
problem by putting \StartSteps\StopSteps (empty pair, and it works also
with \StartStep\StopStep empty pair) right after the start of each section
block, like this for instance: \startbodymatter\StartSteps\Stopsteps
blablabla \stopbodymatter. Could you correct this?

Here is a minimal example illustrating the problem:


\usemodule[pre-60]
\setupinteraction[state=start]

\starttext
   \startfrontmatter
      \startsection[title=My frontmatter section] % <-- Title displayed:
fine.
         \StartSteps
         \startitemize
            \item my item\FlushStep
            \item my item\FlushStep
            \item my item\FlushStep
         \stopitemize
         \StopSteps
      \stopsection
   \stopfrontmatter

   \startbodymatter
      \startsection[title=My bodymatter section] % <-- Title NOT displayed:
bug?
         \StartSteps
         \startitemize
            \item my item\FlushStep
            \item my item\FlushStep
            \item my item\FlushStep
         \stopitemize
         \StopSteps
      \stopsection
   \stopbodymatter

   \startbackmatter
      \startsection[title=My backmatter section] % <-- Title NOT displayed:
bug?
         \StartSteps
         \startitemize
            \item my item\FlushStep
            \item my item\FlushStep
            \item my item\FlushStep
         \stopitemize
         \StopSteps
      \stopsection
   \stopbackmatter

   \startappendices
      \startsection[title=My backmatter section] % <-- Title NOT displayed:
bug?
         \StartSteps
         \startitemize
            \item my item\FlushStep
            \item my item\FlushStep
            \item my item\FlushStep
         \stopitemize
         \StopSteps
      \stopsection
   \stopappendices
\stoptext
