Scrollview with scrolltoRelative automaticaly scrolls

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?! :confused:


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


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

Thanks for help!

Is there No one who has any idea?! :speak_no_evil::hear_no_evil::grinning:
