I tried this in P4_14 and the points did not disappear. So I think this is a Java3D problem. Are you using the OpenGL or DirectX version of Java3D? I think DirectX is not so good with point and line sizes. Furthermore, the effect of setBoxOn() is to make a call to setWhichChild() on a Switch node in the Java3D scene graph. Point size goes into the PointAttributes of every Appearance in the scene graph. These two things should be independent in any correct Java3D implementation.
