I've not heard this before.
Are you saying that you open a .doc file, and can edit it, but not save the changes, because the file is now Read Only?
Or are you saying that when you open an MS Word document, (.doc), you cannot physically make any changes to the document?

Has anyone any idea why all my MS documents would suddenly become locked for editing? I haven't changed a thing, and yet the last 2 times I have tried to edit documents, they have all been locked - even ones that require a password (which I am entering correctly). Going crazy here, please help! Thanks.
