I have a p4 1.7 with 512 ram, using win98. I play Jedi Knight Outcast on the msn gaming zone. Only online---when playing JKO on the zone, my pointer will disappear and my keyboard will stop responding. This is a new problem. The only new hardware...I upgraded a logitech joystick...extreme 3d...to extreme 3d pro. Reformatting didn't help!
