Wpf + Winforms WebBrowser security in Vista

Question

I have a simple WPF app that browses to a web cam. Same issue for winforms app. This works great on XP but fails on Vista ? Looks like IE is doing some sand boxing on vista. With vista the request to install the activeX happens every time but not on XP.

Any one know why or how to make it work ?

Here is the WPF code.

<Window x:Class="WpfBrowserTest.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300" >
    <Grid>
        <!--Grab a web cam view - plymouth!
        OK on XP but fails on Vista ???-->
        <WebBrowser Name="ourBrowser"  Source="http://192.171.163.3/view/view.shtml" />
    </Grid>
</Window>
