Dear Murray,
You need to use RotationAction->"Clip".

e.g.,

Graphics3D[{Sphere[{0, 0, 0}, 1], Sphere[{0, 0, 1.2}, 1/2],
  Sphere[{1, 0, 0.5}, 1/4], Sphere[{-1, 0, 0.5}, 1/4],
  Sphere[{-0.5, 0, -1}, 1/4], Sphere[{0.5, 0, -1}, 1/4],
  Sphere[{0.2, 0.4, 1.3}, 1/8], Sphere[{-0.2, 0.4, 1.3}, 1/8],
  Sphere[{0, 0.5, 1.1}, 1/8]}, RotationAction -> "Clip"]

Best wishes,

Mark
