The problem really is that Stefan is a frequently used first name and Anders is too, maybe not in Germany but elsewhere (up north). :-) Of course the real problem (as opposed to "the problem really") is the indexing algorithm which uses the DBM library for speed. In the current DBM implementation there is a maximum data size which limits the number of objects a key can reference. This does not pose a problem normally as there are only a small number of people with both first and surnames which are frequently found. There are exceptions, especially where first names are used as surnames. Please use handles. We plan to use a different DBM implementation without this limit as soon as possible and after thorough compatibility testing. Daniel
