Tool bar shows both "reply" (purple) and "forward" (blue) buttons active. I have an email message highlighted in my inbox list of messages. I left click on the forward button, an email window opens with the "FW" designator. I type my message, hit send, and instead of a blue arrow, I get a purple arrow displaying on the message in the list. All "forwards" display as "replies".
(I asked this before a while back, but wasn't notified of the responses--which did not resolved my question.)
