Hi Robert, It's good to hear those news ;-)
I'm currently having another problem on removing view (OSG 2.5.2). When closing a view in function void GraphicsContext::close(bool callCloseImplementation) at line 469 if (makeCurrent()) is returning false. False is returned from this workaround added 2008/05/12 in GraphicsWindowWin32::makeCurrentImplementation() if( ::wglGetCurrentDC() != _hdc || ::wglGetCurrentContext() != _hglrc ) { if (!::wglMakeCurrent(_hdc, _hglrc)) { reportErrorForScreen("GraphicsWindowWin32::makeCurrentImplementation() - Unable to set current OpenGL rendering context", _traits->screenNum, ::GetLastError()); return false; } } I wish to know if it is the normal behaviour ?
