I've defined a window like this:

code:

---

<Window Id="Name" Version="1">
    <Attributes>
       <Caption>Bla</Caption>
        <ShowInTaskbar>true</ShowInTaskbar>
    </Attributes>
   
    <TitleBar>
        <AllowMinimize>true</AllowMinimize>
        <AllowClose>true</AllowClose>
            <Title>
                <Text>Message Box</Text>
            </Title>
    </TitleBar>
                ....

---

I can of course show the window etc, nothing wrong with that. But I would like to change the title of the window within my script (the Text Message Box). Is it possible, and how? The Scripting Documentation doesn't say anything about it, and I couldn't figure it our myself...
