I'm in the windows 10 x64 beta and it's working great!
I noticed an issue though, I have my Logitech Bluetooth Wireless Pad set to my "Terminal 2", and normal mouse gestures function on that terminal as you'd expect. But if I do the 3 finger gesture, it executes that action on my "Terminal 1". I assume that's some issue with the gesture event getting away from the device somehow because of the Logitech drivers. Would be nice if you are able to fix it

great job with this though! Aster is taking up basically NO resources on my PC so everything else is running perfectly!
