I've updated my system to 10.10 and since then my "middle mouse button" (on my laptop, under touchpad) is recognized as my "left mouse button". If I open xev, I can see that both, my "left and middle mouse button" are being referred to as "button 1".
Can anybody me to fix this problem and make my middle mouse button behave like a middle mouse button again?

This should allow you to re-map the middle mouse button so that it is properly detected as the middle mouse button.
