Here is what I received from the system maintainer:

"Are you still having problems with these digests? I was working on another project for a couple of months, but now have time to look at this problem. Any help you can give me understanding the history of this problem is appreciated.".

In order to avoid duplicating information, if you are still have problems with the digest, please post any relevant data here, and I will tell him to look at this thread. Thanks.
