[Paraview] Problems with Paraview 3.7-dev: Save screenshot, ExtractBlock in Python

Thu Mar 11 15:19:26 EST 2010

Utkarsh,

I tried it and I get no crash anymore. It seems to work fine now.

Regards

Bastian

Bastian,

I've committed fixed to CVS head. The problem was with the SurfaceLIC
representation and not the ExtractBlock filter :).
