**Chat Text Input

So this happens from time to time; i'm in the main menu and my friends list bugs out. When I finally start typing something to someone in the chat box opens **Chat Text Input is already there. When I do send a message the next time I check the chat box the chat is scrolled all the way up. Along with that, the next time I send a message all the previous messages are in the chat box and it just repeats over and over. Anyone else having this problem?
