OK, another Mac oddity that's got me baffled. Why does Pages or Numbers always ask me if I want to save any document that I've just opened? I've not changed anything, I've merely looked at and read the document! If I click save and then open the document a second time it asks me yet again if I want to save the doc, so I click save again and it now tells me the doc' already exists and do I want to replace it? What's more it often wants to save it in icloud with no other option to save elsewhere that I can see.
