Re: Concepts. We've heard of them. Hopefully.
I had that the other way around.
A user was writing a document, saved the file, printed it, wrote the next document, saved the file, printed it, about half a dozen times. Then screamed and called me to her desk, the first document had disappeared! And she couldn't find the second or third either.
She had diligently saved the file after each document, then deleted the contents of the document and typed the new one! Saving it in the same file each time, just: Print->Save->Select all->Delete->Type new document.
At least she had printed them off first!
