Hi Andreas, I don't use/develop under Windows so I can't provide any first hand guidance. In principle osgViewer::Viewer and CompositeViewer manage the rendering and event collection in a very similar way - they both defer to osgViewer::ViewerBase for the majority of their window setup/and control. Due to the similarity I would have expected things to port across fine, but as you've found out something must being going wrong - so questions like where and why need to answered, unfortunately the hard way by interatively doing tests, setting break points in the code, stepping through etc until we have a clearer picture.
As I can't provide much direct assistance we'll need to call upon other Windows developers to provide some insight. Items like stack trace and the hang point, and ideally an modest code example that reproduces the problem are what are required to help others help yourself. Robert.
