On the http://caliburnmicro.com/ doc page the following example is given but I'm unable to set the related PasswordBox property though my Domain and User properties are set fine. Is there a certain CM version I need for my WPF program?

<StackPanel>
<TextBox x:Name="Username" />
<PasswordBox x:Name="Password" />
<Button x:Name="Login" Content="Log in" />
</StackPanel>

Thanks, Dave
