After signing an PDF file several times, ADOBE 7 and ADOBE 8 showsthat the all signatures are valid but ADOBE 9.2 shows that the first signature is invalid. (only the last signature is valid)
As the PDF file is the same I can conclude that the interpretation of Adobe 9.2 isdifferent from ADOBE 7 and 8. Is that true?
