I have been seeing this message the whole day

Happens when I login.
I suspect something wrong with the code that updates the read/unread posts.
What browser?
Also click on the button “make all messages unread” button as this may fix the problem
I see this on IE8.0.7600.16385
and
FF 3.6.8
Where is the “Make All Messages Unread” button located ?
It is only visible when you have new messages. It is blue, next to the orange “view all unread” button
All I see is the “Mark as Read” - is this the one ?
yeah, does it help?
Looks like it is gone now but I not too sure if clicking the button helped or not 
I will look out and let you know.
