Hi David, When you say the window doesn't display, only a "window with a ?" it's hard to know what you mean. It's certainly now a description I've seen before from users w.r.t OSG app problems.
The best I can suggest is start by getting an OSG example compiling and working that is close to yours and then bit by by modify it. If there is a problem a screenshot would be useful. Also it would be useful to outline the hardware you are working on. Another route would be to just grab OSG-3.2.0 from source and compile it and go from there. Robert.
