> Hi,

> i trying to use the GLJPanel on JInternalFrame which is placed on a
> JDesktopPane. Everthing works fine so far.
> But resizing the JInternalFrame causes some problems. To be more precise: If
> JInternalFrame is relatively small everything works fine and GLJPanel is
> resized correctly. But reaching some critical dimension, the GLJPanel is no
> longer resized in the right way. It seems to me that a part of the GLJPanel
> is not repainted any more. I have checked the dimension given to the
> reshape-method of the GLEventListener and they seem to be correct. Is it a
> bug in GLJPanel or am I doing something wrong?
> Can anyone help me please?
