*bloing*
that was it.
IPTCDigest is equal to CurrentIPTCDigest
removing IPTCDigest (-IPTCDigest=) caused CS3 to show my IPTC Keywords information :) instead of using XMP
I hope Adobe will give the choice back to user to use IPTC or XMP but my feeling tells me that this wont happen :/
thanks a lot :D
