Hi J-W, I'm not a windows user, but suspect that it is the window event behavior of windows that is the problem here, and that the osgViewer's main loop is being held up by calls to Windows to get events. Producer and hence osgProducer has a different backend for implementing events to what osgViewer has (they are two completely different code base) it could be that way that Producer collects events isn't hindered by windows event handling oddities.
I can't suggest a solution, as I'm no windows developer so will have to differ to windows guru's to suggestions on how what the problem might be and suggestions for a general purpose solution.
