Thanks Jean and Peter for replying.
Peter makes a further comment;
"There is a statement in the Preface about using LibreOffice dialogs for opening, saving and printing. However, printing is only for Linux and Mac OSX. Windows version LO 4.0 does not have LO printing dialogs."
I've revisited Preface and will use the same amended text that's used there in my relevant chapter. It now removes the confusion a Windows-only reader could have.
As a final question on this, what is the full menu path used to get to "... Preferences > General"? Is it in "Tools > Options > LibreOffice >Preferences ..."? I'd like to put it in full in the document.
Thanks
John Smith
