Hello, All!

I've stucked with a strange problem with the 'modification details' textbox of the signature properties dialog (the 'Document' tab). The topmost line on the same tab says that the document has not been modified since the signature was applied (revision 1 of 1). From the other side, the 'modification details' textbox reports about '4 miscellaneous changes'. For some signatures (e.g., made by the big Acrobat) the 'modification details' are OK (no modifications).

Unfortunately, Adobe Reader is quite unfriendly regarding error messages.
Does anybody know, what reasons can lead to the '4 miscellaneous changes'
message?

The following information may help (let's refer as 'good' to the signature
made by Acrobat, and as 'bad' to the signature that is reported to have 4
modifications):
a) both good and bad signatures are invisible and are NOT MDP
(certification) signatures,
b) both documents were not modified after the signatures have been applied,
c) all parameters of the both signatures (security filter, subfilter,
certificates) are identical,
d) Adobe Reader 7.0 is used.

Thank you in advance,

With best wishes,
Innokentiy Ivanov
