All my new Excel documents are automatically getting saved as "read-only" somehow. I go to open them, and a dialogue box comes up that says they are "read-only" and are being used by another user. They are not shared with any other users, there are no other users on my computer or network, and I haven't checked any "read-only" options when saving them!
Yes, I've done that. The problem is when I go to the options box, "read-only" is clicked and in grey, so I can't unclick it. And again, I've never set the document as "read-only" to begin with. Somehow the program is doing this automatically.
