This is bug
4309059 - background geometry appears very close to the camera vs 1.1.3
which is fixed in the upcoming v1.2.1beta1 release.
>The second problem is specifically with the DirectX version of Java3D 1.2. It
>works with the 1.1.2 DirectX version and 1.2 OpenGL version. I use a KeyAdapter
>subclass to capture user key strokes to control movement in the 3D space. While
>it has happened before that suddenly no keystrokes were caught anymore (seemed
>to happen more frequently on NT), it is now the case that now key strokes are
>detected at all. The same code works on the same machine when using the OpenGL
>version. I'm testing on a Win2000 PC.

To recevied keyboard event, you need to call
canvas3d.requestFocus();
If it still didn't work, please send us a test case for
investigation.
Thanks.
