In R13 you have options as to how it navigates.
In preferences under navigation, you can select various options.
From the help:
Cursor
The camera will rotate around the selected object point. If you click on an empty region of the scene, the camera will rotate around the screen center at the depth of the last defined POI. This is the recommended mode.
Center
The camera will rotate around the screen center. When approaching the POI, it can occur that the camera freezes in very close proximity of the POI (the POI does not move with the camera).
Object
The camera will roatet around the center of the selected objecs/elements. This reflects the navigation behavior prior to CINEMA 4D R13.
Camera
The camera will rotate around its own axis. It will rotate only and not move.
Hope that helps.
