Have you thought about the multithreading occurring in your
program? Usually with a GLAnimCanvas all of the OpenGL rendering
occurs in the animation thread (driven by the GLAnimCanvas).
However all AWT events like mouse presses are dispatched on the
AWT event thread. It is usually best to simply set up state in
the AWT event handler which is consumed by the animation thread
later. See the JCanyon demo (use Google) for an example of
handling mouse and keyboard presses properly.
