When you put your mouse cursor on the task bar or desktop switcher and roll the scroll wheel it switches between applications or desktops (sorta like when you alt-tab). This is all well and good however I find it to be very irritating because it always happens on accident (I am on a laptop with a touchpad). How does one go about disabling this feature?
I'm using Ubuntu 10.04 with gnome. Nothing fancy.
Thanks in advance.
