Not sure if its a known bug/issue, but ever since the update, any time I come to the site it tells me I have "new messages".  Menu even shows that I have "1 Unread Message", but when I click to read it, it says I have none (e.g there are _no_ messages in my Inbox)

Thanks, no it wasn't a known issue but the unread PM count was out of sync. Should be all fixed now.

That will be the spam message that got sent to everyone..

Spot on. I removed all traces of the SPAM account but that left the unread message count of of balance...
