Why would you say Office can't do anything about?
Let me splain again more slowly:
I open a Word document on a network drive.
I hibernate laptop
Wake laptop in a location with no access to corporate network
Word changes my document to "Read Only" (Says Read Only right on the top of the window)
I edit the document and return to the corporate network.
Word still says the document is read only. There is nothing on the network making the file read only, Word just refuses to write to the original location of the file. Once Word marks a file in memory as read only, there's no way to change it. In the past I would get a warning: "file exists, are you sure?" and I could decide yes or no.

Yes, I can save as a different file name but this is silly. I end up with a dozen versions. It's like Word is working in the 20th century where everyone uses a desktop PC connected to a wired network. Am I really the only one who is annoyed by this?
