i rarely get a hacker in my games, and getting disconnected is prolly your server, and if your using firfox it doesnt work as well. and like akanoob said, holding down the mouse button will make you not lag.
i am having the same problem(replay of tutorial). only thing i did to fix was play on xgenstudios.com and size it and still have kong chat. still cant play on kong, i tried everything. and i played yesterday too.
