Good Question Tim.
Showing the code is always difficult for me, because I encapsulate these 
complex things.
The code I gave above doesn't work either :-)
I use a kill method that also kills the children and seems to be the 
essential thing is this situation,
(btw why are there children ?)
thanks for the tip,
cheers,
