Hi Mark,
Which version OpenGL/DirectX of Java3D are you using ?
This bug is only relevant if you are using DirectX version
and is already fixed in latest release. If you are using
DirectX version, I believe what you see is due to
different fog implementation by driver. Note that
DirectX version of Java3D use pixel fog
(not vertex / range based fog as defined in DX7.0).
