I just bought a Razer Deathadder yesterday. My only (big) complaint is the scroll wheel. On screen it either scrolls down too short, or lags way too much. I use USB Overdrive X, and would like to know if I can change setting on the scroll speed and agility of it. I can't try other USB manipulating software becuase I'm still using 10.3.9 because Steve Jobs wants me to wait ANOTHER HALF A #^%&(#%(& YEAR for 10.5. Thanks guys!
