detaillierte Beschreibung mit Loesung ist meinem vorhergehenden
Posting zu entnehmen.

Hier ein paar 'ungekuerzte Bilder' dazu (vor meinem Bugfix):

Schuckelig, nicht wahr? Der Dienst ist gestoppt und die Shares
stehen noch da. 'Sollte' nicht, ist aber so.

Und jetzt,direkt im Anschluss, mit meinem Bugfix:
