Matthias,
It was my understanding that for scrolling you would create the scroller at the
preOpenCard after you set the acceleratedRendering and the layerMode:
on preOpenCard
set the acceleratedRendering of this stack to true
set the layerMode of group "OptionGroups" of card "Settings1" to "scrolling"
… create scroller here
end preOpenCard
