I dont know what is wrong with the cursor. This is the only code that runing on the cursor:
onClipEvent(enterFrame){
_x = _root._xmouse;
_y = _root._ymouse;
}
So it just can't lock.
Maybe changing quality to low in game menu would help to avoid lag. And i really dont know what is the problem with aiming, in my computer everything works fine.
