The balloon popups have been driving me up the walls lately and I finally decided to google and figured out how to turn it off. This mainly hits a nerve when my wireless drops out, or the ASP.NET Development Server starts up. Using the ‘Run’ command, type GPEDIT.msc, look under User Configuration -> Administrative Templates -> Start Menu & Taskbar then bring up Remove Balloon Tips. From here I would assume you can figure out how to enable or disable this ‘feature’.
