 Since 2.2.1 there has been an annoying, pitched beep, that occurs whenever
 you try to backspace when there is nothing typed into the writing area of
 the conversation window.

 The noise is still present in 2.3, I can't stand to use anything above
 2.2.0 where the noise does not exist. Please remove this annoying beep.
