In Lost Tales the camera will sometimes move on it's own (sideways or down is what I've seen so far). As though the game engine is trying to catch up to a mouse movement buffer. Eventually (after several 10's of seconds) it stop. Anyone else see this or have a solution?

I'm running on Win7x64 Pro, Nvidia, USB wireless mouse. The game is running in XP sp3 compat mode with Nvidia "Threaded Optimization" turned off (so I can get past the initial guards). Except for the camera having a mind of it's own everything else SO FAR seems OK.
