[vtkusers] mfc problem

[Salgado]

Hi All,
I'm testing VTK with MFC (Visual C++ 6.0) running with Windows 2000.
Every time I tested the sample program I got an error. I tested with the
official version (3.2) and with the nightly version with the same results.
This is the problem: When I open some files, I can see the results. But
when I close some of the files, I get the following message: 

Sample - DEC.vtk: Sample.exe - Application Error
The instruction at "0x104c17fc" referenced at "0x000000d0". The memory
could not be "read".

Can someone help me?
Many thanks,
Salgado.
