I need to set up a document to be used as a template.  

I have created the document and saved it as a '.dot'.  I have gone into each
'style' and changed it so that it doesn't have  'normal.dot' as its base.  I
have also unchecked the "automatically update" box.

However, when other individuals open this document and 'save as' to their
drive with a new name, when they make something bold, it 'bolds' everything;
if they center a line, it centers everything, if they use bullet formatting,
it does everything in bullets, etc.   This happens consistently to everyone
that uses the document.  We have to be sure to 'undo automatic formatting'
every time something is formatted.

How can we stop it from doing that?
