I've got a PDF created using Adobe XI Pro. There are some signature fields. The user signs the document and saves it to disk. The one saved to disk maintains the signatures. However, I allow them to attach/email the document and the signatures are gone when the attachment is opened.
Any idea what's going on - and how to fix?
Is Acrobat being used to open the attachment, or maybe something else? If Acrobat, it's hard to say without seeing a sample.
