[vtkusers] Still a Bug in vtkWin32OpenGLRenderWindow ?? -> Solution

[de Boer Ingo]

Hello John,

> I am not sure why CVtkMDIView::WindowProc() is required in the sample.
This is because of the automatic handling of VTK for eg EraseBackground
and OnSize...

What is the original ? Where is it ?
SampleMFC also uses it. And it uses SetWindowID and crashes in the end.

I am not sure myself at the moment. All I need is an MDI application
with double click handled in my derived CView which doesn't crash 
in the end ;)

greets
  Ingo
