[vtkusers] VTK 6.0 with Visual Studio

[Joseph Melnyk]

Thanks for the suggestion.  I can't trace directly into the vtk dll's for more information.  The stack trace just tells me where they've failed in the .h file, which is just the New() call.

As I said, some objects will instantiate and can be used just fine.  For example, I can use vtkTable and vtkFloatArray just fine but then when I try to use vtkContextView or vtkInteractorStyleTrackballCamera, the New() event fails.

Regards
Joseph Melnyk
