I've already updated the Synapse to the latest version.

The wheel (middle) button is fine, but when I push the the wheel button to right or left,

nothing happens. I tried to assign other functions to the buttons but none of them worked.

(My original setting is: right -> Show Desktop, left -> Alt+Left)

I even bought a new Naga to replace this one, but the result is the same.

I started using this mouse and computer about 3 months ago,

everything was fine, don't know since when this happend.

Any idea to solve this problem?
