Thanks, however my mouse section already looks the same. Still, the scrolling is not very fluent, its more like jumping a bit and then doing nothing. Upward scrolling doesn't work at all and the downward one is random and choppy.
I guess X just doesn't handle these new optical&generally weird mouses very well...
I've been looking at these instructions:
But that is a bit outdated regarding usb and "scroll stick" mice.
I'm gonna try out a few more Options when I get back home:
Option "Protocol" "usb"
Option "Buttons" "3"
Option "ZAxisMapping" "4 5 6 7"
to see if they make a difference.
