David, Can you take a look at TestTemplates.py. It is failing on all platforms reporting: 298: File "/Users/lorensen/ProjectsGIT/VTK/Common/DataModel/Testing/Python/TestTemplates.py", line 112, in testVector 298: self.assertEqual(r[2], 2.0) 298: TypeError: 'vtkRectf' object is not subscriptable Thanks, Bill
