Is it possible to deactivate the message that appear when you close the document, asking if we want to save it? I need the users not to keep the document, never. But it´s really confusing for them when this message appears....
One workaround for this is unchecking "Save Document (Users)" under Settings, Document Properties, Security, but it will work if you have some kind of security (section access) in your document.
I'd rather distribute them a limited access copy, as I understand you are not working with QlikView Server. Do they need to reload? If they don't, check both sheet properties to avoid them making changes to the document (right click, sheet properties, security).
