SMS notification sound

[drewden123]

I have a 6700 w/ wm5 and i know that to have your own notification sound for SMS you must put a .wav file in the \windows directory of the phone. I did this and I noticed that when you read your sms, the phone continues to play the sound/song until it's finished. I was wondering if there's a registry tweak or somethin that could make the phone stop the sound once if you read the text while it's still playing?
