I have not tried with the latest version yet. I found this problem in v3.7.7. I'll try that and let you know.
If the problem is still there, I'll send you an example.
Thanks for the help,
Simone

1) Is this with the latest PETSc? some of these issues may have been fixed.

2) Please send use something that reproduces the problem and we will fix it. We aren't aware of this problem.
