Another Word tic. If you try to open a big document, get bored waiting and then double-click the original document to open it again, you’ll eventually get a document up with the query from Word:
Do you want to revert to the saved [document name]? Possible answers No and Yes, with No the default.
Except I don’t understand the question. How can I be reverting to something I haven’t changed? Does it mean I’ll lose changes, if I had made some? It’s a really bad dialogue box.
