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
Regards.
