Thank you. I used the vtkFileOutputWindow and got the following error
messages:

ERROR: In \enthon\src\Vtk-5.0\Rendering\vtkWin32OpenGLRenderWindow.cxx,
line 238
vtkWin32OpenGLRenderWindow (01237AF8): wglMakeCurrent failed in
MakeCurrent(), error: The handle is invalid.

ERROR: In \enthon\src\Vtk-5.0\Rendering\vtkWin32OpenGLRenderWindow.cxx,
line 129
vtkWin32OpenGLRenderWindow (01237AF8): wglMakeCurrent failed in Clean(),
error: 6

Can anyone tell me what is going wrong? The code is below, it works fine
on Linux, but on Windows I get the errors.
