I have not heard of this particular problem, however I do suggest the following as it causes similar problems in DD.

If CAPS LOCK is on . . . the camera will no longer follow your character. Turn CAPS LOCK off to return camera to normal.

Hope this helps, I was so disappointed with BD that I never finished it . . . =)

Edit: I should add why CAPS LOCK does this. You could put the CL's on and move your mouse pointer to the edge of the screen which caused the screen to pan. This would allow you to search for locations / items etc without having to walk your character. I never really found it to be that useful myself. Turning CL's off after panning would pop the screen back to your start location with your character centered.

Many who start DD with the CL's on experience this unusual behavior and don't realize what is happening. I "assume" it was a feature in BD as well but I never tried it in BD. CL's was a bad choice for this feature key as the CL's could easily be on when you started the game. Unless you knew what was causing the camera to act this way it could be disconcerting at the least.
