Microsoft Word - Winword.exe Using High Cpu When It Just Idle?

Ok I am sitting here watching taskmanager, winword.exe is hovering between 10-11% cpu usage (with it now in background idle) and 20% or more when I do activity in a winword window.This seems abnormal a word processor needs so much cpu power even when just sitting idle, to give you an idea 10% on my current cpu would probably equate to about 80% on my laptop's celeron which is absurb for a word processor.I currently have 10 documents open, it seems to use about 1% per document, all documents are text only and average 1 page long.
