Flash smooth scroll help please

Hello all...

please help...

I found a tutorial for a great smooth scroll
in this page:


I got it to work when I click and drag the bar to scroll...working great...

here's the thing:

I would like the scroll to work with the mouse wheel as well just like in the tutorial page. There's no mention anywhere in the tutorial codes about the mouse wheel and the author is sadly not responding.

any suggestions,
here's my FLA (flash 8) and SWF demo...15k


please help

ps: I've tried to incorporate the "mouselistener" function, on my own...I can't get it to work
