A family of Microsoft word processing software products for creating web, email, and print documents.
After spending an hour messing around with this I finally found how to turn the annoying thing off. The icon showed up in the Authoring and Proofing tools. I clicked on it and the Disable button was there. Turned that sucker off! It's now grayed out on my computer. (It better not come back!)
I tried to attach screenshots but they fail to upload.
