I am writing a document, from scratch (not editing another file).  Every time
I try to format a line (like preceding the next section), the entire page of
text reformats.  I have tried deleting checs on boxes in Autocorrect and Auto
correct while you type, and gone in to all the other options under the Tools
Options menu, removed the track changes tool bar and looked at the revealed
formatting.  Still can't get this to stop "spreading" the format changes.  
Help!
