We are seeing an issue with Adobe Reader 9.x, whereby we have documents that are digitally signed. I can validate the signature and get a "green" tick to say it has been verified. I then close then save and close the document, but when I reload the same document (pdf) in all cases the document requires to be re-validated so the green tick is displayed again.
I have done various searches online for someone experiencing similar issues but no results as yet have been found. If anyone has seen this please can you respond and help identify what is going on here.
We are seeing this on both WinXP SP3 (32bit) and Win 7 SP1 (64bit). And have tried using Adobe Reader 9.x, Adobe Reader 10.x and Acrobat 10.x with the same results each time.
