well, please try the CVS version

or wait till 2.8.3 is release ...

HINT: the gl4java.applet.SimpleGLAnimApplet
reacts in the double mouse click on the canvas with:
	- remove the GLAnimCanvas of its parent container
		- GLContext will be destroyed here !
	- create an own frame
	- add the GLAnimCanvas to the frame
		- GLContext will be created with the first view ..

i hope this helps ..

but the upper action _is_ debugged within CVS only ...

cheers, sven
