#14 3D interface silently crashes

[gw-]

Under MS Windows XP Professional SP2 (x64) (and probably also elsewhere) with Java(TM) SE Runtime Environment (build 1.6.0-b105) the 3D interface does not work! Every time the 3D interface tries to initialize itself and display it silently crashes with:

Using the GUI view.
Creating default configuration file...
Done.
