To repeat: only one person can have a document open for editing *at one
time.* What you are experiencing is normal if two or more users are trying
to open the file simultaneously. If one is opening and closing it, and then
another is unable to open it for editing, then this would not be normal.

I understand that only one person at a time can open the file for editing,
however in previous versions, if I tried to open a file that someone else us
already using, I would be prompted letting me know the file was already
opened and given the option to "Open as Read-Only or Open a copy."
Now it simply gives the message "Filename cannot be found. Please check your
spelling or the path"
