Hi Ren, I know nothing about ActiveX/IE as I haven't been need coding on Windows for a decade so I can only work with guess. My best guess would be that perhaps the refresh is causing the destruction and recreation of the graphics context, but the OSG hasn't been told about this so it retains all it's handles to the original OpenGL objects and then tries to use them - but they've all be deleted so you get a crash.
