Live Update = Small Issue

Hi everyone Clicked Live Update this morning, had a 99MB update that downloaded without issue on Win XP. When I turned the PC back on hours later, I noticed that the Norton Icon in the system tray is taking forever to show the green tick…I never had this issue before this mornings large update, any idea what happened? Norton is working fine but having to wait some time to get the green tick is bugging me. Thanks.
