I got into similar trouble dealing with a data file including quadratic
hexahedrons some time ago and the suggestion from Mathieu Malaterre was
to use VTK from CVS.
<br>I've not tried that yet hoping that version 5 will solve the problem.
<br>May be the same problem exists with quadratic tetrahedrons.
