Got a question about the "Clear Signature":
suppose I have a stand-alone (a pdf file, not in the WorkSpace) PDF form with 2 Signature fields,
each Signature locks a few fields on the form,
user A signs his Signature, gives the PDF file to user B, and user B signs it also, then returns the file back to A.
now, A right-clicks on the Signature and selects the "Clear Signature", and all his fields are unlocked,
then A makes some changes to his fields, and signs it again.
so, now the form has some new data, with an old Signature signed by B.
that's a problem, because B might not agree with the new data.
How to prevent this from happening?
i.e. is there a way to prevent A from altering the form after B has signed it?
thanks
