[vtkusers] vtkPolyDataConnectivityFilter

[R K Shyamprakash]

Hello,
           I am using vtkPolyDataConnectivityFilter as follow.

		vtkPolyDataConnectivityFilter con = new vtkPolyDataConnectivityFilter();
		con.SetInput(polyData);
		con.ScalarConnectivityOff();
		con.SetExtractionModeToAllRegions();
		con.Update();
		con.GetNumberOfExtractedRegions();

But often when I call Update(), the program crashes. I am using VTK with
Windows NT 4.0. I saw similar problems being posted in user's archive list.
But could not find a definite solution. Can somebody help?

Thanks
Shyam
