Sounds great, although that sentence seems to have a wrong parity of negations. Anyway, great that you found the time to work on ghosted vectors. I'm currently trying to test the ghosted vectors on my application, but the queue on the cluster is full, so I have to wait. > Besides, this can't be the right fix, can it?

Perhaps one should apply VecCopy to the local form (obtained via VecGhostGetLocalForm())? Also, I wonder whether other methods, such as VecScale(), might possibly suffer from similar problems? I'll ask in the petsc-users list and let you know what they say.
