Does anyone know how to set the notifications behavior on the EVO? Specifically with Google Talk? I would like the phone to beep at me only once when someone sends a google talk message, and then not ever again for the following messages until I unlock the phone's screen and reactivate the google talk app. I think it already works this way for email, but not for Gtalk. Can this be done? And, I already know that if I open up the chat session, the sounds shut off on successive messages. However I would like it to stop the beeping without opening the chat window.
