Using Acrobat Pro 6.0, I created a form with 6 text fields and a submit form button. Works fine on my Mac, when opened with Reader on Windows on PC, it gives "operation not permitted... " when "submit" button is clicked. All usage rights are allowed under "document properties." All fonts except a Helvetica are embedded. User cannot save form even if submit button is removed.
