Attached is some ugly sample code (just a hacked HelloUniverse.java) to
show that JPopup works with JDK1.2.2 and Java3D1.1.2OpenGL.
Note that
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
must occur before the new JPopupMenu as it only affects JPopupMenus
created after the call, any created before are still rendered as
lightweight popups.
The problem Tachio describes with it only displaying when the JPopupMenu
intersects the edge of the Canvas3D is exactly the behaviour you see
with a lightweight popup.
Hopefully the sample code will stop a few of these questions for a
while.
