title: Why WPF controls not same scroll bar styles?
body: <p>I have a WPF WebBrowser control beside a WPF TreeView control. Both have default styles with default properties. I have not changed anything except placing them on my WPF window. If you view the screen shot below you can see the two controls have two different scroll bars. I have no idea why this is happening. </p>
  
  <p>Is there a way to make one control's scroll bar look like the other, or just default them both to windows styles?</p>
  
  <p>Thanks</p>
