LiveUpdate say no new updates but still "Restart Now" button

Norton Security just installed five days ago.  Ran LiveUpdate this morning and this is strange.

---

Check for Updates - Completed

Download Updates - Not required (grayed)

Process Updates - Not required (grayed)

Two buttons:  Restart Now, Restart Later

Shown a top, "a previously installed update is awaiting restart"

I see no reason for this.  I will Restart, according to the button, anyway.  (Windows Vista, laptop, already did two LiveUpdates after installing Norton Security "five" days ago).
