I need a new mouse and I'm considering this one.

The only thing I'm unsure about are the drivers. Do they adequately allow you to configure the buttons? I'm a lefty so I switch them. I need games to recognise this.

I have a Razer and the buttons are anyone's guess. Some games recognise the reconfiguration. In others they're default (left = left) and in some the left mouse button just doesn't work at all.

My Logitech was... adequate. But now it seems to be doubling the number of clicks I make. So I'm not too sure I want another one as I'm not sure where the fault lies - the mouse or the drivers.
