Hi Roger,

just to leave your quick and helpful reply not unanswered:  I was hoping
for faster processing to be able to answer your question whether further
changes are needed.  For the moment I just say thanks for your kind
cooperation and I might (or hopefully might not) come back to you in
case of further issues.

Kind regards

       Andreas.
