I have a user that is using Acrobat Professional 11 and it has worked flawlessely for quite awhile. But recently when he goes to try to sign the document it allows him to draw the signature box but as soon as he releases the mouse Acrobat crashes and immediately closes. If he goes into the Signature section of preferences and changes it between DKC #7 and CAdES it works for that instance, but the next time he opens a document he has to repeat the process otherwise it crashes again.
Anyone have any thoughts?
Windows 7 Professional 64bit.
