Indeed it does.  Thank you for putting some time in to testing and producing
an excellent problem report.
I have not put as much time into testing and polishing the DDF implementation
as I would have liked, partly because there doesn't really seem to be much
interest. 
But reports like this make it a whole lot more interesting.

I will try to look at this some time soon and let you know what I find in the
code - feel free to remind me if you haven't heard in a week.

Thanks,
