Hello again,

I have an 3D Plot which uses an older version of JOGL. Now I have included this Plot in an applet which i want to display on a webpage.

It's all fine and the applet starts without any error messages. But there's nothing to see, too. the page is just white.

in the java console i see, that the applet starts correct and the init and start methods are called.
The data for the plot is correct.

i just get an error when closing the tab :

Any idea what might cause this strange behaviour?
