I have a Verizon 8130 after having a 7130. I'm almost positive that when I would reply to a mesage on my desktop (Outlook on Exchange) besides having the reply show on my BB as it does today, it used to mark the message I replied to as open. On the 8130 it is not marking the message as open though. I end up with my reply made on my desktop showing on my BB but the original message shows as unopened on my BB.

Am I nuts and it wasn't like that on the 7130 or is there some option I don't have set that allows this?
