asp.net 2.0, updatepanel, wizard, rendering problem nach postback

[wolfchr3]

Hallo,

Ich habe eine asp.net 2.0 website, wo ich ein wizard-control innerhalb eines updatepanels verwende.

Leider melden Anwender im Internet, Probleme beim Rendering der Website, wenn sie auf den Button next des wizard-controls klicken (postback).
Es fehlt auf der nächsten Seite der Text und der Tabelleninhalt!

Alle meine Tests mit allen Browsers funktionierten soweit.

Wo liegt die Ursache?

Danke
Chris
