I tried the code addition in each of my 4 canvases (canvasi) but I still have the same refresh problem...it still has a delay before I regain control of the window. Do you think it may have to to something with the GraphicsConfiguration? or is there something else that I could be doing wrong?

We had a similar issue with our canvas. This code seems to have fixed the problem. When you create your Canvas3D, over-ride your paint method like this: GraphicsConfiguration gc = getGraphicsConfig(); canvas3d = new Canvas3D(gc) { public void paint(Graphics g) { super.paint(g); Toolkit.getDefaultToolkit().sync(); } // paint() }; // Canvas3D Hopefully that will solve the problem for you.
