Chat bug [CLIENT]

Whenever I'm chatting with a friend or in a queue chat, my chat keeps getting saved. It does a constant copy/paste plus whatever i am sending.

1. Right click on friend and select chat.
2. enter text to send and hit enter
3. enter new text to send and hit enter -- sends new text PLUS old text; continues copying and pasting all old text along with new text.

--note: this also occurs in queue search chat box.

This occurred my entire time logged in tonight. Since adding Rek'Sai.
