Igor,

Thanks again!  I tried reading the ECMA spec but .... Arrr it was not fun
reading.  I am surprised at how tricky some of JS, I always thought of it as
a simple version of java!

I will modify my code to use the setParent and to call setPrototype(null).
Other than the 'side-effect' that the any variables created without the var
will always get put in the top most parent scope are there any other
possible issues I might bump into?

Cheers,

Stuart

p.s. When the product is finished I'll try and get you some product
description to put on your web site so that you know all your help was not
wasted!

If you want to force numeric semantic of "+" then
rootCounter = Number(rootCounter) + 1
is enough.

Yes, but do not forget to call <anonymous-scope>.setPrototype(null) in
that case.
