226 |*      das der Anker auf die Veraenderung des Flys reagiert. Auf diese
227 |*      Reaktion hat der Fly natuerlich auch wieder zu reagieren.
228 |*      Leider kann dies zu Oszillationen fuehren z.b. Der Fly will nach
229 |*      unten, dadurch kann der Inhalt nach oben, der TxtFrm wird kleiner,
230 |*      der Fly muss wieder hoeher woduch der Text wieder nach unten
231 |*      verdraengt wird...
232 |*      Um derartige Oszillationen zu vermeiden, wird ein kleiner Positions-
233 |*      stack aufgebaut. Wenn der Fly ein Position erreicht, die er bereits
234 |*      einmal einnahm, so brechen wir den Vorgang ab. Um keine Risiken
235 |*      einzugehen, wird der Positionsstack so aufgebaut, dass er fuenf
236 |*      Positionen zurueckblickt.
237 |*      Wenn der Stack ueberlaeuft, wird ebenfalls abgebrochen.
238 |*      Der Abbruch fuer dazu, dass der Fly am Ende eine unguenste Position
239 |*      einnimmt. Damit es nicht durch einen wiederholten Aufruf von
240 |*      Aussen zu einer 'grossen Oszillation' kommen kann wird im Abbruch-
