I'm using a jpac and playing last night and today in several different games the buttons and joys quit responding correctly. They would either get stuck doing the same thing repeatedly or not do anything at all. Last night it even did it after Mortal Kombat 2 had been sitting for a quite a while and was running attract mode. I had to push the esc button repeatedly to just get out of the game. I do have a solid red light on my jpac if that means anything.
