Trying out Win 8.1 and the mouse behaviour is really weird. It didnt work, then I restarted, it worked, then I restarted, didnt work. Sometimes, it works, sometimes it doesnt. Sometimes you can see the cursor on the screen and it doesn't move, but the wheel scroll and mouse buttons work, sometimes, the cursor isnt there, sometimes the red light on the mouse doesn't even turn on, sometimes it works. It's just so fucking random!

What's going on there? Mouse: wmo of course.
