Help getting collision/near/touch/anything actuators to reset?

I can’t for the life of me get the collision/touch actuator to reset. If one object touches another, and then they quit touching each other, I can’t get Blender to realize that they stopped touching each other. I’ve tried using the Near actuator too, but to no avail.

I’m making a first person shooter. When I point at an object and shoot, it works. The problem is, if I point at an object, then look away and shoot, the object still reacts as if it’s been shot. Does anybody have any idea why my actuators aren’t resetting, if that’s even the problem? Any help would be greatly appreciated. Thanks.
