Everything is fine in windows.. I see you have a new version up, I'll test again when I've upgraded. Also having issues with the K95 when an external monitor is also plugged in. The monitor doesn't get any signal. Though I think this is an OS issue, as I've had the problem even without ckb installed. I'll also try with a usb hub as I'm wondering if only plugging in the cable with the keyboard icon is causing some weirdness.
