...But how can the mouse laser calibrate with the surface, if you don't move it? Seems kinda pointless! For the record, I've just had to completely reinstall Window 10 Pro after iCue crashed, my LS100 lights stopped working, as did my LT100 towers, AIO and RAM sticks. The only Corsair things that worked were my keyboard and mouse. I couldn't even uninstall iCue as it just did nothing. Alas, I'm now trying to calibrate my Dark Core RGB Pro SE and the surface calibration glitches and then crashes at around 50%, shows the USB cable disconnected and then the mouse reboots. It's bloody frustrating to say the lease, but be rest assured that you are not the only one! CORSAIR.....PLEASE FIX THIS ISSUE!!!!!!
