Hi Rik,
I actually read that Wolfgang had written, but there is some confusion for
me. Indeed, my environment uses a frame and Wolfgang said to be used \
starthanging ... \stophanging rather than \placefigure. But my text contains
a blank line which is to create a new paragraph and so I should use \
placefigure !!!
