Slideshows and Chapters

I have a flowchart that includes 1 timeline and 3 slide shows.
On the flowchart they all appear as C1 and are correctly connected through their
end actions and from the menu.
When I preview, I can skip the timeline video to the first slide show with the
Next Chapter button. But within the slide show the Next Chapter button forwards
to the next slide like if every slide was a chapter.
Is there a trick to make each slide show = 1 chapter?

I don't think I get it - DVD Studio Pro doesn't allow a slideshow to have
chapters?

Sounds reasonable, Ruud.
