PM Bug is Back

The legendary PM bug is back. Checking my Unread folder and there is nothing there, but shows I have 1 unread message. Hover over the the Mail Icon on top of the page and it says "No New Messages."

Windows 7 Home Premium 64bit

Waterfox 16.0.1

I'm already on it in another thread.

@video_game_king: Ok. Didn't see the other thread. If a mod wants to lock this and link the older one, go right ahead.

Back? This bug has always been here for me.

It never left. But a lot of people are having issues with the PM system falsely reporting numbers of unread messages. I have 21 "unread" messages, myself.

Just one? I've got 54.

I saw a message earlier saying that messages in outbox were marked as unread, could you check if that's the case?
On my side, the count has been pretty accurate

Maybe it's some kind of secret lottery?

My number is 5!
