A bypass to what? Renaming the original.doc to a .html extension doesn't change the file type. Try it. Save a Word document, change the extension to .html, and open it in your favorite plaintext editor. Not much you can do with it there. Now open that same .html file in Word, and MS Word correctly identifies it as a Word document by its header (even though it has a .html extension), and the document protections still apply. -- Leif Gregory --------------------------------------------------------------------------- Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts!
