David, I am afraid I build against the Producer_1_0_0_release_revision_1 tag. _renderSurface->shareAllGLContexts(true); has no affect in windows at this revision. It might be an idea reverting to the OSG and Producer 1.0 release base and seeing if you still have the same problems. Your problems might be something to do with sharing contexts between threads. You might also try setting the flags that cause Producer to single thread (and use the same thread for setup). Have you thought about using the pBuffer support in osg::CameraNode instead of using Producer. If you use osgUtil::Sceneview there is one at the root of the scene graph by default, although I have only used non frame buffer rendering in ones further down the tree myself. If you go down this route all you have to do ensure that you have a valid rendering context available to the thread that you call the osg on. If you need to share a rendering context between threads remember that you must release it from one thread before grabbing it for another.
