Thank you for your answer. :)
Yes it does work very well on one object at a time. For a selection, not
so well here. Unfortunately I have only three minutes of freedom left
for now. I'll explore the causes when I'm back in about 10 hours time
and let you know the results. In any case your script has everything to
solve the problem for me in the most elegant manner that is afforded to
us by the API. Yeah!
