Norton 2009 System Tray Icon Gone

I have Norton Internet Security 2009 installed on Windows 7 RC build 7100.  Recently, the Norton icon with the little green check has dissappeared from the system tray.  The program still seems to work normally, performing scans and updates regularly, but it concerns me that the icon isn't there, as it always has been before.  I have checked the startup items and anything else I could think of, but nothing has worked.  I've even reinstalled the software twice, but nothing has changed.  Is this an intentional feature of the latest build of Norton that was designed for Windows 7 (16.7.2.11)?  Any insight would be appreciated!
