OK, but that is also strange simply because the button calls the
scene.save(...)! Anyway, glad you figured a way to get this working.

With IPython from SVN I am unable to reproduce this. What does happen
for me is that my history gets all messed up if I create a
mlab.figure(). I can't hit up arrow and what I've typed is lost. I
suspect there is a problem with the embedded interpreter and ipython.
Not sure, perhaps Fernando can help.

Hmm, it is possible that the AA feature is hardware/driver dependent
although I am not sure how exactly. I use nVidia cards, VTK from CVS
and everything works fine on linux and the mac.
