I can't scroll down with the mousewheel

[quinnten83]

I must have done something really stoopid (yes with oo), because I'm unable to scroll down using my mousewheel.
Scrolling up seems to work, but scroling down doesn't, it will start to move, but after that first jump it stops and nothing happens.
I configured my compiz some, but didn't do anything out of the ordinary (I'm thinking maybe there is a plugin that is conflicting?).
I checked the mouse settings and the keyboard shortcuts, but couldn't find anything out of the ordinary.
Can you guys please give me a hand? Because this is really really annoying....

Is it the mouse? Try a different mouse or try your mouse in a different pc?

*forehead slap*
it might be the mouse or the kvm switch I'm using.
I get the same thing in the other computer.

if you type xev in the terminal and try to scroll in the white box is there any output from terminal?

Some types of active KVM switches do not emit signals that exactly match the physical keyboard, monitor, and mouse, which can result in unwanted behavior of the controlled machine(s). For example, the user of a multimedia keyboard connected to a KVM switch may find that the keyboard's multimedia keys have no effect on the controlled computer(s). Likewise, a monitor connected in this way may be detected as an incorrect model, or not detected at all; this may cause issues for operating systems that rely heavily on boot-time "Plug n' Play" detection of this hardware, such as Ubuntu.

Sometimes, but not much.
But it's okay, as long as I know it's the KVM switch, I can live with this little inconvenience.
