title: WPF Animation Duration
body: <p>I have a storyboard like the following</p>
  
  <p>
     Duration="0:0:1" Completed="DeviceExplorer_Completed">
     
  </p>
  
  <p>The animation for some reason does not appear to be working linearly.
  If I change the duration to something like Duration="0:0:0.8"</p>
  
  <p>and assign the stroyboard to a MouseEnter event of a button, the animation moves but does not complete for some reason, I move my mouse over the button a few times before it enetually completes...</p>
  
  <p>Any ideas why?</p>
