GraphicsLayer MouseLeftButtonDown doesn't work

Hi everybody,
An other question?

I have a Map in my Home.Xaml.
I have a ribbon in my MainPage.Xaml.
Every time, i click on my map, the event on mygraphicLayer doesn't work:

<esri:Map x:Name="MyMap" >
            <esri:Map.Layers>
                <esri:ArcGISTiledMapServiceLayer ID="MyLayer" 
                Url="http://services.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer" />
                <esri:GraphicsLayer ID="MyGraphicsLayer" MouseLeftButtonDown="GraphicsLayer_MouseLeftButtonDown">
                </esri:GraphicsLayer>
            </esri:Map.Layers>
        </esri:Map>
<esri:Map x:Name="MyMap" >
            <esri:Map.Layers>
                <esri:ArcGISTiledMapServiceLayer ID="MyLayer"
                Url="http://services.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer" />
                <esri:GraphicsLayer ID="MyGraphicsLayer" MouseLeftButtonDown="GraphicsLayer_MouseLeftButtonDown">
                </esri:GraphicsLayer>
            </esri:Map.Layers>
        </esri:Map>

I don't know why ?
The event for the MyMap works but it doesn't work for my graphicLayer.
Thanks

Is your map surrounded by a ScrollViewer? If yes, this thread is related: http://forums.arcgis.com/threads/8575-Pan-Doesn-t-Work!!!

The ScrollViewer intercepts Map's MouseEvents.

No, my map isn't in ScrollViewer.
It's very strange.
I can click to the MyGraphics for take the information of the object but with the layer layNeigh, i don't.

 <esri:Map x:Name="MyMap" Loaded="MyMap_Loaded">
            <esri:Map.Layers>
                <esri:ArcGISTiledMapServiceLayer ID="MyLayer" 
                Url="http://services.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer" />
                <esri:GraphicsLayer ID="layNeigh" x:Name="layNeigh" MouseLeftButtonUp="LayNeighMouseLeftButtonUp" />
                <esri:GraphicsLayer ID="MyGraphics"  MouseLeftButtonDown="LayHistoricMouseLeftButtonUp" >
                    <esri:Graphic Symbol="{StaticResource SelectMarkerSymbol}" >
                        <esri:MapPoint X="-140.9" Y="63.391" />
                    </esri:Graphic>
                </esri:GraphicsLayer>
            </esri:Map.Layers>
        </esri:Map>

An idea?

Both MouseLeftButtonDown and MouseLeftButtonUp do not work for that layer?

Is there maybe another MouseLeftButtonDown or MouseLeftButtonUp event that is marked Handled somewhere in your code? Could it be because there's no graphic where you clicked?

oth MouseLeftButtonDown and MouseLeftButtonUp do not work for that layer?
Yes. Two events don't work with that layer.

Is there maybe another MouseLeftButtonDown or MouseLeftButtonUp event that is marked Handled somewhere in your code? Could it be because there's no graphic where you clicked?
There is no another event in the page.

Can i send you my project , if needed !

This GraphicsLayer contain graphics? When you click on a graphic, the MouseLeftButtonDown does not get raised? I could not replicate it. Please share some code.
