I have a Logitech Mouseman Wheel, but the wheel does not work to scroll in the demo unless I exit the controller software (which handles double clicks, and other non-standard functions assigned to buttons), by hitting ctrl-alt-del, then ending the "em_exec.exe" task.
I have no problem with my logitech mx 700, maybe you should update your mouse driver <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" />
