Hi.

Anyone having problems with using Animator to update the screen in an applet?

It works fine on windows, but on OS X it fails with:

“Error: view not ready, cannot lock focus at “src/native/jogl/MacOSXWindowSystemInterface.m:createContext:50”
net.java.games.jogl.GLException: Error creating nsContext

I used to have this a while back and patched this in my local version when I used to use JOGL. The problem is that the applet is trying to paint before the OpenGL context is actually ready to paint - its a semantic problem between Windows and OSX that can be solved by not trying to pack, size, etc. the drawing area until it is visible.
