The icon didn't match the text. The english version was ok. > +) I signed the same PDF manually with Acrobat Writer 6.0 and 7.0 and > this problem does not appear > You may not be signing the same way as iText. > +) Not being lazy I tested it with the german and english version of > Acrobat Reader but this doesn't make any difference > It did in the case of Joachim. > +) Quite interestingly the number of changes are depending on the usage > of visible/invisible signature.
