I have a form that I built in LiveCycle Designer ES4 and the latest revision I made to the form caused an issue... one of the form users is unable to digitally sign the form, but he used to be able to. I can't figure out how to enable the form for digital signatures. After I "Reader Extended" the form, all of the signing tools are grayed out. I believe the form user has Adobe Reader XI.
How do I get the form to allow digital signatures again?
