Hi everyone is my first post.  
Fuse is very good tool. Good work Fuse team.

Fuse Version:  
Fuse version 0.25.5 (build 7677)

I used CircularRangeBehavior and have problem on Log.  
What I do wrong?  
Please see log below.  
Thank for help.

My Code

```auto

<RangeControl Width="100" Height="100" HitTestMode="LocalBounds" ux:Name="mySlider">
    <CircularRangeBehavior MaximumRadius="410" MinimumRadius="100" StartAngleDegrees="100" EndAngleDegrees="410" />

 <DataBinding Target="mySlider.Value" Key="value"/>
    <Panel ux:Name="thumb" Margin="4">
        <Rectangle Color="Red" Alignment="Right" Height="20" Width="20" CornerRadius="4" />
    </Panel>

    <ProgressAnimation>
            <Rotate Target="thumb" Degrees="380" />
        </ProgressAnimation>
</RangeControl>

```

Log

```auto

Hi, and sorry for the late reply. I can’t reproduce this in Fuse 0.28, so I assume it has been fixed since 0.25. Please let us know if you still get this problem after upgrading to 0.28.
