I just placed a simple RadWindow on my app (code below). When I run it I get this exception:
"Invalid attribute value ManipulationMode for property Property. [Line: 290 Position: 17]"}
"Invalid attribute value ManipulationMode for property Property. [Line: 290 Position: 17]"}
<telerik:RadWindow x:Name="GameOver" Placement="CenterCenter" PlacementTarget="{Binding ElementName=LayoutRoot}" IsFullScreen="false" WindowSizeMode="AutoSize" />
