Hello Ke Li, yes, if the mouse is moving when you release the button the model rotates continously. This is a feature that is really nice for quick presentations where you want the audience to look at the dazzling stuff moving around on the screen instead of listening to your rambling. It is part of the osgGA:TrackballManipulator and there is no soft way of changing this behaviour. However it is easy to subclass TrackballManipulator or write your own cool Maniuplator, possibly using TrackballManip for reference. For the feature you want to disable; look in the TrackballManipulator::handle() method for a GUIEventAdapter::RELEASE event.
