When the Halo window loads up, the Halo title picture is stretched, and when going to the multiplayer setting, no picture is there. The mouse icon disappears. If I click join game, it doesnt work.

Also, the chat is gone.

I know the chat thing, i can fix it. Its just the image thing happened once before, and I fixed it. Now I cant remember, so if anyone can help me I would be glad.
