I’m on Windows 7 and in every place I go to whenever my mouse idles the mouse disappears and the gamepad pointer shows up on the screen:
do you have a gamepad plugged in when this happens? if you do can you try unplugging the gamepad and see if the same behavior occurs?
Oh, that would be the problem. I had plugged it in for Dark Souls and completely forgot I had one connected. Sorry 
its all good, this shouldn’t happen even if you have a controller plugged in, need to work on the deadzones for active gamepad use detection.
cough menu-configurable deadzones?
