    I have trouble with digital signature compatibility.

    I know about HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Signatures\XPCompatibleSignatureFormat , and I set it.

    I save my document in Word 2010 in 97-2003 format and sign it after that. If I open this document in Word 2010, it detect that document have correct MD5 old format signature. But if I open this document in Word 2003, it detect that document have digital signature but this signature not valid: signature incorrect or document was changed. If I use Word 2003 to sign document, this signature valid in Word 2003, but not valid in Word 2010: document or signature was changed. How I can fix it?

    I use russian Windows7 and XP_Pro OS, Office 2010 Standart Edition, russian Office 2003 Standart edition.
