I'm using a Logitech cordless gamepad and it works perfectly usually for about 2 hours or so then it starts "sticking", or the controls don't respond at all. Anyone else having issues like this or know what might cause this? When I re-start it works fine.

Batteries dying?

That was my first thought, so I switched them out and it's still happening. I might try a corded xbox controller and see how that works.
