<Button IsDefaultButton="true" Location="312,520" MinimumSize="10,10" Name="Repeat" PackLocation="right,bottom" ScrollExtent="42,42" Size="42,42" Style="Styles.Repeat.style" Visible="false" />
<Button IsCancelButton="true" Location="312,520" MinimumSize="10,10" Name="Stop" PackLocation="right,bottom" ScrollExtent="42,42" Size="42,42" Style="Styles.Stop.style" />

Would changing the red above to be the following move the repeat button to the center instead of being right over the stop button?:
