Danny - thanks! it works though I am not sure I fully understand what i did
:-)

I am iverriding teh opener class with my fancy one, then creatign an opener
instance of it, and then i am specifying the addheader method you mentioned.
is that the right way to do it (well - it works) - and what did i just do in
terms of class overriding ?

thanks a lot for your help!
