The window is created prior to the CreateDevice call but is not yet shown. It has the following Window Styles and Extended Styles: WS_CAPTION WS_CHILDWINDOW WS_VISIBLE WS_CLIPSIBLINGS WS_CLIPCHILDREN WS_SYSMENU WS_THICKFRAME WS_MINIMIZEBOX WS_MAXIMIZEBOX WS_EX_LEFT WS_EX_LTRREADING WS_EX_RIGHTSCOLLBAR WS_EX_MDICHILD WS_EX_WINDOWEDGE My application is an MDI application and the Direct3D window is an MDI child. I have found that the mfctex sample in the DirectX SDK also stops with this error. Let me know if you need any further info. Thanks Mark
