IN THE LAST COUPLE OF WEEKS, ALL OF A SUDDEN WHEN I SEND THE GOVERNMENT A REPORT (I'M A GOV CONTRACTOR) THE RECIPIENT CANNOT SIGN. IT WILL NOT LET HIM SIGN IN THE SIGNATURE BOX. IT LET ME SIGN AND SEND, BUT WILL NOT LET HIM SIGN AND RETURN AS ACCEPTED. CAN ANYONE OFFER SUGGESTIONS??
Which version of Acrobat/Reader you and your recipients use? If it is version 11.0.09 it may be caused by the tightening of the processing of certificate restrictions in 11.0.09. See my reply in the sign with a smartcard discussion.
