This may be a bug (I am unsure) but when trying out the content samples there is a demo where some balls (silver) are placed on a floor with a moving box (in blue) using a ping pong motion. When I grab a ball and slowly drag it around there are occasions where it seems the mouse doesn’t know where it should be. It begins jumping up and down insanely fast. Sometimes it even causes the ball to lock in “picked” mode so that I no longer need to keep the mouse button down. It will remain in “green” and keep on bouncing up and down. I am using Windows 8.1, all the latest patches etc… An old logitec mouse (Logitech-mx518-mouse) 16gb ram, 3.5 Ghz cpu 8 threads. This happens when simply installing the sample and the editor provided in standard fasion, no changes of any kind.
So if anyone can shed some light on this, I would be grateful.
Best regards/
Mike
