Hi,

can you Give your Code to Reproduce this.

I tried this without Specifying BackGround but i was not able to.

Here is my code.(I tried this with a Empty Scroll Viewer also)

 <Grid x:Name="LayoutRoot" Background="White">
        <ScrollViewer x:Name="myViewer" VerticalScrollBarVisibility="Visible"  HorizontalScrollBarVisibility="Visible" Height="100" Width="200" MouseMove="myViewer_MouseMove">
        <Canvas Height="1000" Width="1000">

            <Button Height="50" Width="50" Canvas.Top="500" Canvas.Left="350"></Button>
            </Canvas>
            </ScrollViewer>
    </Grid>

Hi,

I checked your code and able to see same thing.

Then i checked msdn:(http://msdn.microsoft.com/en-us/library/system.windows.controls.scrollviewer_events(VS.95).aspx)

 "Mouse Move Event For Scroll Viewer :Occurs when the coordinate position of the mouse changes while over a UIElement (or while a UIElement holds mouse capture). (Inherited from UIElement.)"
