I am not sure if they were using the new MRJ, an old version, or none at all. This question has popped up several times on the board before, and every time, the question has gone unanswered. It came to my attention again when this post appeared.

All of the people who posted were unregistered, so I doubt we'll be able to contact them directly. ¿Maybe we could post a reply to the thread asking them to give us info about their MRJ? If they do visit the boards frequently, then they might see it and respond with the info you need to discern the cause of the problem. Just a suggestion, though. :-)
