Scrollview with scrolltoRelative automaticaly scrolls

[treviz]

Hey there!
I have a ScrollView and in this a StackPanel with a LayoutAnimation to Scroll the View to the Bottom. It does what it should, but my Problem is, that when i scroll up and reach the top, it automatically scrolls all the way down to the bottom. What am I doing wrong?!

Code:

   <ScrollView ux:Name="myScrollView" SnapMinTransform="false">
    	<DockPanel>
    		<CogWheelReload Dock="Top" />
    		<StackPanel Dock="Bottom">

                        ........

                <LayoutAnimation>
    				<Move RelativeTo="PositionChange" Y="1" Duration=".5" Easing="QuinticInOut" />
    				<ScrollTo Target="myScrollView" RelativePosition="0, 1" />	
            	</LayoutAnimation>
          </StackPanel>
       </DockPanel>
    </ScrollView>

Thanks for help!
