I currently have a PDF I created that has a signature which closes the fields once it is signed. I selected the "Extend Features in Adobe Reader" so that it could be completed, signed, and saved in Reader. It all works as intended. However, once the document is signed in Adobe Reader, it saves over the original. I fear this will eventually result in the original template being lost. How can I correct this (i.e. prohibit the user from saving over the original in Adobe Reader)? In other words, how can I force a "Save As" window to come up after they sign? Thanks!
