As you all know MT has been really really slow lately due to the dramatic increase of traffic. As a result, a solution is to remove the "messages notification" feature found on the top right side of the site. Before you go crazy yelling and screaming, you can still check ur new messages by clicking on the "Messages" link on the right navi bar under your name. This is only temporary as once Sheqel can get MT a new faster server then we can have that feature back, in MT v2.2 .
For now, please live on without that feature (i really liked that feature myself too XD) for a much faster MT experience. ^_^
