Menus are not heavy weight in Ubuntu

[acardona]

In the visualization tab, the 3D Window (an AWT component) paints over the menus (a Swing component). One way to fix this is to declare menus to be heavyweight:

If I remember correctly, the surprising solution is to invoke a static method of JPopupMenu class, which addresses issues with all menus:

JPopupMenu.setLightWeightPopupEnabled(false);
