Scroll wheel as middle mouse button.

[Harold L Hunt II]

Staf,

The middle-click functionality of the mouse wheel is highly driver 
dependent.

For example, I have Microsoft Intellipoint installed (you can use it 
with other mice, I believe) and I have left the wheel click as 
"AutoScroll (default)".  Clicking the mouse wheel works just fine in X 
applications.  However, clicking the mouse wheel in Win32 Emacs causes 
the little AutoScoll symbol to appear instead of pasting.  If you click 
the mouse wheel again, the AutoScroll disappears and the pasting occurs. 
  If you change the wheel click to anything other than the default, then 
pasting in Win32 Emacs doesn't work at all (IIRC).

So what does that make us?  Nothing.  :)

Back on topic --- the point is that I have only had good experiences 
with Intellipoint in wheel click behavior.

Now, for your particular case we may be able to find out if the Logitech 
drivers are registering a new mouse message for wheel clicks.  If that 
is the case then we can query to see if that message has been registered 
and start handling it if it has been registered.  If you can do the 
detective work on this (look on Logitech site, MSDN, etc.) then I might 
be inclined to polish it up into a fix for you.
