No NIS icon in the notification area at startup!

When the system startups, NIS(Norton internet security) icon is not sown in the notification area, and even I click the Norton Internet Security icon on desktop, it does not respond!

I think this problem occured after updating to NIS 22.5.4.24 (on October 2), and it occurs at least one time at the first power on everyday, but it disappear after the manual restart and the icon appears in the notification area, and it seems everything is OK.
