I am also having issues with putting multiple signature fields, locking
all but the unsigned signature fields, and when someone clears thier
signature, it unlocks all the fields, but not the previously filled in
signature fields. Is there an answer to that? Seems like a bug. I am
using Acrobat pro x to create the document and save with extended
features and require that the first signature locks all fields EXCEPT
the remaining signature fields. This works ok until someone clears thier
signature ...
