Hi, I know this has been brought up in the past but the issue persists and nothing seems to have been done to address this so far. When I initially bought my Orochi (the 8200 dpi version) in May the surface calibration didn't work at all - the mouse didn't react to anything I did in synapse calibration tab, staying at max liftoff range and causing any movement in z-axis to send the cursor flying diagonally across the screen. The support couldn't help me back then, so I attributed the problem to incompatibilities with my old PC (running Win 7 x86). Now I got a new laptop with Windows 10 x64 and, as I expected, the calibration works perfectly... except that it stops working everytime I reboot, or even wake the computer from sleep. It goes back to hardware default settings, even though the profile is still there and settings are unchanged in Synapse. The only way to fix this is to recalibrate (I don't use any Razer mat) every single time I get down to work. I've seen this issue brought up here months ago with almost every single mouse that uses Synapse 2.0 and it still persists to this day. Has anyone found a workaround solution to this problem so far? Can we ever expect a fix in the future? Is the fact that it completely refuses to work on 32-bit systems any clue to why it bugs out?
