Hi Jason, Good to hear you've found a solution. Managing the events with a composite viewer is a bit more complicated because of deciding who gets the event focus. The API of osgViewer::View/CompositeViewer probably needs evolving to make it easier, exactly what it should look yet I can't say.
Putting an osg example together that does something similar to what your app is doing would probably help out with provide an awkward test case that pushes the current viewer usage beyond what it can do comfortable now. Once we have a good example we'd then be able to look at refactoring osgViewer to make the example cleaner, and make life for users following on from yourself just that little bit easier.
