[vtkusers] 3D axis that follows main actor

Fri Sep 10 04:34:23 EDT 2010

Hi,

My app crashes when I add a new tab, before showing the scene.
I wrote an example and... does not crash (axis_.py).
Then I wrote another example (note.py) with a wx.aui.AuiNotebook and it
crashes after adding the scene, when pasing the mouse over it.
