title: Autoscroll problem on mousedown
body: <p>I have a custom control inside an autoscroll panel. When the user control extends beyond the width of the panel, the scroll bars appear. When you then scroll any distance, and mousedown on the control, the scrollbar snaps back to 0. Does any one know why that might be? I'm pretty sure I am not trying to change the value of the scrollbar anywhere...</p>
  
  <p>Thanks</p>
  
  <p>EDIT: This only appears to happen once, the first time you click on it, every other time it works as expected</p>
  
  <p>EDIT 2: It also happens when you bring a new window up, and then go back to the C# window</p>
