Steve,
I have a static PDF I created in LiveCycle ES and did utilize the signature collection tool to add several digital signatures (PKI) to my form. However, RadioButtons do not seem to always lock with the signature collections, even though they have been included in the collection the signature is applied to. Sometimes the RadioButtons do completely lock, but most of the time they do not. This also happens if I convert the RadioButtons to checkboxes.
When I modify the RadioButtons after locking them with a digital signature, Adobe does point out that the form has been modified (most of the time).
Any ideas on what may be the issue?
Dan
