Good to hear you got it working. It is a problem. In my, and others', opinion it is a *bug* that the onPrepareDialog is not called when a dialog is restored on a configuration change. onCreateDialog is called when appropriate, but onPrepareDialog is not....
I think the onPrepareDialog should ALWAYS be called just before a dialog is shown, whether it is through an explicit call to showDialog (x) or through the restoration management of the activity.
