I created a disciplinary action form that requires multiple signatures without necessarily locking the form. While testing the form I developed two challenges; one is that Adobe X hangs up indefinately everytime I try to sign a document, the other is that I lose the ability to attach documents and toggle radio buttons.
System Config: Win7 Adobe X Pro Reader/LiveCycle Designer ES2
What version of Acrobat and/or Reader is this? Reader-extending the document from Acrobat does not allow you to add attachments in the free Reader you'll need to use a server product to allow attachments in Reader.
