This comes with the VTK examples!

OK. I see that this is true. I don't want to get involved with the MFC code,
because this is a part of an MDI program and perhaps it was the intention to
make the vtk window a child of the frame or parent.

Because it is const ? GetSafeHwnd() just returns m_hWnd

just the concept of setparent(parent)
setwindow(window) rather than setparent(window)

...

I am a little worried about the title of the thread "...Bug in
vtkWin32OpenGLRenderWindow..." because I don't think there is a bug. I
suspect that some misuse of the class is more likely. I have apps with 5 or
more windows in which have no crashing problems or anything similar.
