Smart Ping Mouse Bug? Please help!!!

So, I just bought a new Razer Deathadder mouse. When I play league in game and use "G" to smart ping, my mouse cursor will fly to a random location on the screen. As you can imagine this is very troublesome when playing the game. I've seen others post with a similar problem but have yet see any of them answered. Also this only happen IN GAME on LoL. If anyone also has some knowledge in general about optimizing mouse tracking and accuracy in game it would be much appreciated. Someone please help me get this figured out asap! Thanks :)
