[vtkusers] bug with multiple render windows?

On or about 16 Dec 2002, I started to get a VC++ assertion and message 
(Win32/MFC/VC6:Sp5), when calling m_RenWin->Delete() in a destructor: 
 
   "pure virtual function call" 
 
m_RenWin is a "vtkWin32OpenGLRenderWindow".  Since I only have at 
most three Vtk Views, I just commented the offending line, but it 
may be related to the issue you identified. 
thanks, 
Nigel
