Windows live mail plays a sound every time it checks for new Mail instead of when new mail arrives.  This has happened since I had to delete my Hotmail account and reinstall it to WLM due to the messages suddenly not downloading from the server.  I do not really want to turn the sound off but it really isn't serving any purpose where there is not actually any mail.  I'd like to know if there is a fix for this or a configuration tweak to put it back to as it was before.  Help appreciated
