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
