Document keeps turning into a "Read only"

[Balliol]

I am working on a very long document and every so often when I go to save it a message comes up saying that it is only a "Save Only" document. I get away with it by copying it, pasting onto another sheet and giving it a different name but surely I shouldn't have to do this. Whats causing the problem?

The message suggests that there might be left-over lock files (created by Word as you edit a Word file) on your system. These files may have been left behind after a Word crash. See http://www.gmayor.com/what_to_do_when_word_crashes.htm.
