Thanks Paulo! I changed VERISIGN_SIGNED to WINCER_SIGNED. That removed the plug-in message. Acrobat didn't recognize the Verisign root certificate until I changed the security settings to use all Windows root certificates. Does that jive with your experience? You must tell Acrobat who do you trust. I still can't get the signature graphic to display. Are there any rules for the image format, size, or color depth? No matter what I try, I don't see an image. It will work with a taller rectangle. Your rectangle is too narrow. Paulo Thanks!
