I cannot replicate this. Nor can I think of any way it could happen.

Does this happen consistently or you, or was it a one off?

Must have been something wrong on the server side. It's working now.

Sorry for bothering you.

[JimmXinu]

Okay. But FYI, I'd run a memory tester if you are having other weirdness happening.
