[Insight-users] itk vtk and cocoa

[Sean McBride]

Please keep the discussion on the list.

I work on a similar application and have no such problems.

Which compiler?  Which version of ITK?  I have success with gcc 4.2 and
ITK 3.8/CVS.  Do you have a simple test case showing the error, for us to try?
