I am using Word 2003 SP2. I received a document that was read only.
Since I needed to edit it, I did a Save As (but did not change the name),
unchecked the read-only box in the Properties under Attributes, then selected
my personal hard drive.
I was able to edit the document and save all subsequent changes.
The next day when I opened the document the read only was back and I could
not make changes without saving under a different name.

I then tried to copy the contents of the document to a new Word document,
but the read only is preserved. Doing a Save As results in the same scenario
as above.

How do I save this document and kill the read-only option?
TIA
