Given a new Silverlight project targeting .Net Framework 4 with references to Telerik.Windows.Controls, Telerik.Windows.Controls.DataVisualization and Telerik.Windows.Data (build 2011.1.404.1040).
MainPage.xaml:

                        <layer:HotSpot X="0.5" Y="0.5" ElementName="PART_Frog" />
                    </layer:MapLayer.HotSpot>

                <layer:MapPolygon Points="44.361404418945312,25.968851089477539 45,25.968851089477539 44.361404418945312,26 "
                               Stroke="Red"
                               StrokeThickness="1"/>
            </layer:InformationLayer>
        </map:RadMap>
    </Grid>
</UserControl>

From zoom 16..20 the rectangle is sliding across the map, leaving the road. How can i stop this?

Hi Sorin Mecu,

Unfortunately we aren't able to reproduce the problem using your XAML and latest internal build of the RadMap control. We have a couple problems with HotSpot which have been fixed few weeks ago. Could you, please, test your application with latest internal build? 

Kind regards,
