[JAVA3D] program stops when calling SimpleUniverse.getPreferredConfiguration

[Martin Frey]

Hi all Did someone already had the same error when calling SimpleUniverse.getPreferredConfiguration() after Picking ?   I can make as many JInternalFrames with a Canvas3D in it as i want. And there is a call for the GraphicsConfiguration. I implemented a Pickbehavior which returns me the TransformGroup of the picked object. This works too.   But i now create a new JInternalFrame ( the same ) my program is running for over 10'000 years or so.   Is this a bug of Java3D or awt or did i something wrong?   Thanks a lot   Martin
