What happened was i changed both the chat keys (team and global) from T (global) and Y (team) to Y (global) and U (team) so that i can press the right button when i go to type a insult (too much CS...)

Well, it kicked me in the pants by bringing up the chat history or... something. IDK, but apparently the global chat thing was up there as well, and everything that happened would be put as a new line on the chat history (the messages at the top were the oldest)

So i had a bunch of text and useless info scrolling on my screen as the game went on and people killed eachother, and i couldn't move because the global chat thing was up. I tried clicking, moving the mouse, pressing the function keys, and nothing would remove that damn global chat and history. Not even the [enter] key!!!
So, knowing that something was screwed up, i changed the chat keys back to T (global) and Y (team), the chat history went away, and i was able to kill players again.

Anyone else get this when they changed their chat keys?
