Notification popups and sounds

When I receive a notification to tell me I have a new message, it looks and sounds like a "system notification" from my laptop - is everyone experiencing this?

I see, I turned off the sound notification there but I am still receiving the loud laptop "system notifications". I was reluctant to turn the whole thing off

Yeah... I think what CDT really needs is a way to play a sound on new message without showing a notification. Or maybe don't show the notification if one is already being shown.
