If you're using Microsoft Office, have installed AutoTag, and it does not show up in the top set of tabs, it's possible that the application has somehow become disabled. To re-enable it:
Go to the Office button (the big button in the upper right corner) >> Word/Excel/Powerpoint Options >> Add-Ins
Does Windward AutoTag show up under the Inactive or Disabled Application Add-Ins? If so, select "COM Add-Ins" or "Disabled Items" from the drop down menu and click go. From there, please re-enable Windward AutoTag.
