It happens all out of sudden, yesterday i am playing the same game, same save using the same computer without changing any hardware and software setting.
Today, once i open the game, load the save i played yesterday, then the camera started to pan strictly and without control
i can't even scroll up to the original position
i even load up the mission pack save provided, but it have the same problem too
i can't attack or use skill if the camera just pan down to the edge of the map everytime i unpause the game

First, reboot your computer. Next, check your mouse (clean it thoroughly). Sounds like a mouse or mouse software issue to me.
