Hey guys...wondering if anyone has this problem. I am playing SF2 or any 2 player versus games and while we're playing...both sides start to move by themselves or sometimes even just block or freeze. It seems as though the players are stuck in position during gameplay. I turnd off the sticky keys on Windows XP in the control panel thinking it would resolve the issue but it doesn't. I also replaced ALL of my buttons/joysticks on my cabinet and it seemed to work a little better but it seems to come back here and there. I usually update my gamex everytime I turn on the cabinet. Any help would be appreciated. Thanks.
