Dear Virgil,

the classes GLCanvas (and therefor GLAnimCanvas) in the package
gl4java.awt,
adds itself as a mouselistener, to repaint if:
	mouseClicked
	...

So, if you use GLCanvas or (especially) GLAnimCanvas, 
just overwrite mouseClicked with a no operation implementation,
or whatever you want to do.

I made this as an easy solution for the incomplete window refresh,
if an "own window" is used and it is shown again after hidden by another
window.

Yours, Sven
