Conversation Not Locking

Hey Everyone,

I'm having a problem that I can't sort out... Multiple submits are being processed simultaneously. My understanding is that conversation locking should prevent this from happening, however that's not working. See below:

Any ideas out there?

Perhaps I just needed to walk away from my computer for awhile. I am unable to reproduce this problem anymore... I'm going to go ahead and pin this one on the ghost in the machine.
