Good question: Have you overwritten configInitOSWindow?

Otherwise you should have an AGLWindow, which implements the proper  
makeCurrent() to set your GL context. As a quick hack, you can try  
calling 'getWindow()->makeCurrent( false )' early in your frameDraw().

You can check the following:

- AGLWindow::configInit() returns true
- AGLWindow::makeCurrent is called
- Your rendering code does not do aglSetCurrentContext( 0 )

Since the Equalizer examples don't have that issue, something in your  
code is messing up the GL context.


HTH,
