The question mark or tick mark shown by Acrobat Reader 8 in place of Digital Signature is feature releated to Acro Layers which is not available in latest versioons of Acrobat Reader. If you are looking for component which can show the tick mark or question mark in Acrobat Reader 8, a free web application component along with complete integration code for web browser based digital signing from usb token is available from my company, details of the same is available at http://help.signer.digital/digital_signing_and_authentication_from_web_browser.htm
