By the way, if you follow the link to the invalid document in Dropbox:
https://www.dropbox.com/s/7g34odmhxm6044k/Janet.docx?dl=0
and then just click to view it in Dropbox, it will seem fine. To see if the signature is any good, you'll have to download it and the open it with Word.
When you open it with Word, there will be a yellow line that says PROTECTED VIEW Be careful--files from the Internet can contain viruses. Unless you need to edit, it's safer to stay in protected View. (in a box) Enable Editing
At that stage, the signature line is blank. If you click "Enable Editing" and wait a moment the invalid signature will appear. |
