Hi Clement, This issue is likely to be due to lack of proper clean up of the graphics context and GL object ID's that the scene graph carries around with it. osgViewer's built in windowing functionality supports the proper clean up but it's like your own MFC code won't be doing all that is required. This topic has been discussed a number of times over the years, and I even wrote about it to another user today so please check the archives, including todays posts for further information.
