Issues with a few items

Hi there,

I've created my forum during the weekend and im now having a few issues.

1. Im trying to change the images of the buttons in the navigation bar at the top, all the buttons have changed ok except the Message button which everytime i try to change i get this message: "You must provide a menu name". Now i can see a name i there for the menu, and i cant change it as the box is readonly. Help?

2. A few of my members are saying that when using IE it keeps logging them out constantly and its getting reall annoying.

3. Anyway of placing the Chatbox on the portal page?

Thanks for your help in advance
