title: JavaFX Scene Builder Menu object not draggable
body: <p>I'm new to JavaFX and SceneBuilder.
  In SB, I'm trying to place a Menu object in a AnchorPane with a drag and drop and this operation is not being possible as no menu object instance is being dragged.
  Also, no drag and drop is being allowed also to the Hierarchy pane of the Library accordion.</p>
  
  <p>The AnchorPane is the one placed by default when the tool is started from NetBeans "new - empty FXML".
  This problem doesn't exist to other objects, like buttons.</p>
  
  <p>I'm using Ubuntu 14.04 </p>
  
  <p>with:
  NetBeans IDE 8.0.2 (Build 201411181905)
