Some of the quick controls (Silent Mode) are missing from the pull up window in the notification icon on the taskbar

I used to be able to turn on the Silent Mode by right clicking the Norton Security icon on the bottom Windows XP taskbar. That feature is now gone and now I have to open the Norton Security with Backup application, select Settings and check off the Silent Mode to turn it on.  When did this change or do I have a problem? Far too many steps now!
