sudden change of font color, script changes all now underlined in yellow font

  1. working on long doc this am. box notice appeared on screen asking re long doc taking longer time to make changes did I want to see changes right away…opt yes or no. I checked yes…entire doc changes now underlined and appear in yellow. How do I recover and reset to regain doc as previous without yellow font and inderlining or showing all changes as such?
  2. three dark bars appeared suddenly on page 177 and will not delete…hi-lite/delete not effective

You may have Track Changes turned on. See this post.

Go to the “View” menu and uncheck “Track changes”.
