The parameter Field in the OnDataChange-Event has irritated me. I
thought, it will always give a reference to the fields, that have
changed and not, that it is null, when two or more fields have changed.
When you use KeyDescLinks, always at least two fields will change and
then the field-parameter is null. I'm not sure, that everyone is aware
of that and therefore a short note in the help-file would be helpful.
