.. or the Context is allready being used by another thread !
E.g., you have a GLAnimCanvas, the context is being used
by your rendering thread and you use a JVM with native threading !
Then you press a button, and your action listener trys to occupy the
allready occupied context !
Thats it !
To avoid this ... just out all stuff in the display() method
and use flags ! Or just be sure, that you give your action
a chance the next time ...
