Scrolling does not work with Logitech Cordless MouseMan Wheel in Ubuntu Karmic Koala

[Edgar Gijselaers]

I'm using ubuntu linux 9.10 for two weeks now as a Linux total beginner,
and i don't seem to get my sroll wheel to work with my Logitech Cordless
MouseMan Wheel.
Strange thing is that is has worked two times, but i don't know why it
suddenly worked and neither why it stopped working again.
Does anybody know what to check or configur to get this working again?
Thanks for replying,

Edgar
