Wow Michael !,
Just d/l the zip file and took a look at the script -- very nice!
Small, clean and to the point. Much better than my clumsy attempts!
Now to try it out....
Thanks much --

Paul

p.s. - I also wanted to compliment you on the docs you've written so far -
you have a talent for explaining the functions and concepts very clearly!
That's something not seen very often --
