I'm running Vista 64 on my iMac C2D along with a Logitech MX1000. On the Mac side, I've got two of the mouse buttons bound to volume control (up and down), which I find very useful and is natively supported in Logitech's Mac OS X software. However, on the Windows side, I can't figure out any way to do the same thing. SetPoint doesn't seem to have any way to bind a button to volume control and I haven't been able to find any keystrokes that control volume in Vista besides the special function keys (which are only supported by the boot camp drivers and so aren't any use here). Anyone have any idea how to do this?
