Yes, I repeat, No ;-) Using the brown handle will move a morph within its
layer, e.g., the brown halo handle is a distinctively non-destructive,
non-DnD gesture. However, the Wonderlands wants distinctive drag and drop
gestures. Thus taking the system window either by the black handle _or_
grabbing it on its title will work but the brown halo want.
