I am sorry I cannot reproduce your problem. Can you come by the NOC (6th floor, room "Studio 5") so we can work on this together?

We've spoken with MCR extensively, and I sat beside him and could not replicate his problem. He's aware that we're interested in any continuing problems, and will contact Con or Colin if it comes back up again.

Resolving this ticket for now.
