I've just done a desperate 10 minute google session on behalf
of someone who has a wheel-mouse :) and found the following
link, and thought I'd share, just in case others run into this
problem. (I came to this thread via google, btw ;}).

Preety good info, really, and a quick summary as follows:
Unless you install and use iWheel the behaviour of the
wheel-mouse for scrolling is an per-application setting.
Ways to set the wheel up per app are given on the website
above - enjoy.
Cheers,
