It would be nice if the button in the task bar would blink on and off when an invite is sent in the gaming mode. This way I wouldn't have to listen to that annoying elevator music for the invite when browsing other places on the web.
Hi Skeeter,
You can turn the background music off in the game options or use the MUTE button in the lower left hand corner while you are searching for a game.
That also mutes the invit sound. At least when I use the game options to mute ambient music, mutes it all.
