Hi Richard, The trackball slows as you move into the origin as the rate of movement in is always a percentage of distance from the center to the eye point. This is just the way it works, it's not some that can be "fixed" as it's doing exactly what it's meant to do.
Now if you want some custom manipulator that kinda behaves like the TrackballManipulator then you'll need to subclass or just write your own from scratch. One hack you could implement is the pushing forward of the center as you get near to it, rather than just keep reducing the distance between the eye and the center. Robert.
