Rotating Control and Map Zoom in WPF

Hi,

I am having an issue where after rotating a UserControl by 90 degrees and by changing it's xy axis to rotate in it's center, when I zoom the map, the UserControl will not stay in the same point.
I am using WPF .NET 4.0 and ESRI Client Beta 2.2

Here is my XAML:

<Grid x:Name="_rootElement" Background="Transparent">
        <Grid.Resources>
            <Storyboard x:Key="_rotateAnimate">
                <DoubleAnimation Storyboard.TargetName="_rootElement" Storyboard.TargetProperty="(Image.RenderTransform).(RotateTransform.Angle)"
                                 From="0" To="0" Duration="00:00:03" />
            </Storyboard>

        </Grid.Resources>
        <Grid.RenderTransform>
            <RotateTransform x:Name="_rotateTransform" />
        </Grid.RenderTransform>
            <Image x:Name="_image" />
    </Grid>
</UserControl>

Here is the code behind:

    public void Rotate(double angle, double x, double y)
        {
            _rotateTransform.CenterX = x;
            _rotateTransform.CenterY = y;

            Storyboard story = _rootElement.Resources["_rotateAnimate"] as Storyboard;
            DoubleAnimation da = story.Children[0] as DoubleAnimation;
            da.From = _currentAngle;
            da.To = angle;
            story.Begin(this);
            _currentAngle = angle;
        }

Can anyone tell me what I am doing wrong ?

Thanks
