I'm just guessing here so if this idea isn't workable just chalk it up to my ignorance. Wouldn't it be possible to encrypt the document text (which I'm presuming is between some sort of tags in the open file format) based on whether a password had been applied. After all, again guessing, if the document creator chooses to apply a password to the document isn't the password stored in encrypted form in the open file format? I'd be quite surprised to learn that document passwords are stored in clear text. If the password can be encrypted and stored then why not the document text? -Alan
