Hi, I'm Phil the main developer of JAva3D. I've looked into this and for the life of me I can't get a middle mouse button to register a drag on a component no matter what JDK I use, below is my code.

So I guess whatever was registering your middle mouse button (and the loss of it) is something specific to the JVM and JDK you are using. Sorry I can't be more help here.

The EventCatcher will only fire on a mouse motion drag event and the MouseZoom requires the alt key to be pressed at the same time, so perhaps some flavors of Linux pass this as a mouse middle button drag event, and the MouseZoom was being helpful.

public static SimpleUniverse createUniverse() {
                GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
                Canvas3D c = new Canvas3D(config);
                SimpleUniverse univ = new SimpleUniverse(c);
                univ.getViewingPlatform().setNominalViewingTransform();
                univ.getViewer().getView().setMinimumFrameCycleTime(5);
               
               
               
                MouseMotionListener mml = new MouseMotionListener() {

                        @Override
                        public void mouseDragged(MouseEvent e) {
                                System.out.println("my one! " + e);
                               
                        }

                        @Override
                        public void mouseMoved(MouseEvent e) {
                                // TODO Auto-generated method stub
                               
                        }
                       
                };
               
                c.addMouseMotionListener(mml);
                return univ;
        }
