Shoutbox

I do beleive that the plus! notifications are interfering with MSN notifications

1) When a contact signed in msn would show that he did
2) I also wanted different sounds for signing in
3) I set sounds for each group in my list using preferences >> notifcation >> Sounds
4) now when a contact signs in, I only see the pop-up saying he/she has signed in about 2 out of 10 times but I always hear the sound.

Any suggestions??
