We circulate many 'approval documents' that each VP etc, must 'sign' and then forward to the next person in the routing list. Some signatures make it in the transmission sequence and some do not, it is blank where they had typed in their name. I don't think it is reattaching the newly signed document that it opens in Word. The doc is pulled out to a folder, signed, saved there, and left behind there. If we try the test again, it will ask if you want to overwrite the one that is already there. This worked in 7. All versions of 8 now have shown this behavior, it is intermittent, sometimes you sign it and sometimes it doesn't for any given user. Using 8.0.2 client now.
