currently I are using Adobe pro 8.0 with LiveCycle Designer 8.0. i created a form in LiveCycle with digital signatures that would lock the form after signing...but when i save as a PDF and extend to Adobe reader, the form will not lock after a digital signature is used. Most personnel utilize Adobe reader. The form is not on a server. Any help would be appreciated.
You need to make sure that you create a field collection, and then assign the collection to a signature field with the "Lock Fields After Signing" option selected. You create the field collection from the "Object" palette of the signature field. See attached screen shot.
i think it worked out!
