title: MouseDown/MouseMove/Click Issues with Flex Drag and Drop
body: <p>In Flex 3, I have an ItemRenderer that has a button in it. I want users to be able to click and drag this Renderer, but also just click the button.</p>
  
  <p>Right now it's working with the Renderer listening on "MouseMove" to initiate drag and drop, and the button listening on "click".</p>
  
  <p>However this is very screwy. If somebody is dragging a scroll bar and comes anywhere near that renderer, MouseMove gets fired on the renderer and initiates dragging.
  (or if somebody is resizing a HDividedBox, basically if someone initiated a click anywhere in the app and rolls over this renderer, we get unwanted dragging. </p>
  
  <p>The alternative is listening on MouseDown instead of MouseMove, which fixes the previous issue, however the nested button loses it's click. I can click on the button, but the renderer just thinks it's time to Drag.</p>
  
  <p>Is there anyway around this?</p>
