Hi Rahul, Use the low level stereo support in the OSG that you'll current get when using HORIZONTAL_SPLIT will mean that the viewer itself will just know about one camera across both screens, while the low level SceneView implementation will split it in two. As the viewer's camera treats the whole window as one, the events will run across both as if it's just one hence your problem.
To get the mouse events to behave like their is one one window you'll need to get the viewer to do the stereo, using two slave cameras that both share the same window, with this window stretched across both screens (or one one each screen if you have two graphics cards). Such an approach for stereo at the higher viewer level is where the OSG is headed, but as yet I haven't had a chance to implement this. Robert.
