Hello Shirley, others
Did you ever get your problem solved? I'm suffering the same since years:
Select a word or line, then for example Control B for bold and the entire document bolds. Click on undo arrow and the document unbolds; only the selected piece remains bolded. A paragraph mark is added to the footer each time this is done. (Using W XP and O 2003, both fully updated.)
It appears the problem is residing in each doc file, also in rtf. A file started on another machine is free of this problem also when I copy it to my main machine. A file made on my main machine and copied to the other carries the problem along.
While closing a file I'm often requested to save changes while I made no changes, like a virus trying to get piggy backed.
I'm in the mood now to get rid of this problem. It is a real pain.
Thanks for advice.
Johannes
