I just got a Razer Imperator mouse and downloaded the version 1.0 drivers for it from Razer. The control panel has settings for sensitivity, acceleration, polling rate and the lighting (scroll wheel and logo), but none of them work. I can change any setting I like, but when I close and reopen the control panel, they are reset to default. The mouse is working but the sensitivity/tracking speed isn't quite right, but nothing I do seems to affect it. Also when I restart my computer, I'm told I have either no mouse plugged in or have a keyboard plugged in that is not recognised. Unplugging and re-plugged the mouse fixes that. Is anyone else using this mouse? Does the control panel work for you, or do you use some other control panel/driver/extension?
