Hi Jeff,

I'm trying to figure out how to implement a version of Dragboard.setDragView() 
that works with JFXPanel (which isn't currently supported). Years ago I did 
this in Swing by creating a window that followed the mouse around (at an 
offset, so it wouldn't take all the DragOver events).

I created a Popup Window and added an ImageView, but I can't figure out how to 
get the equivalent of DragSource events. I thought I could just call 
source.startFullDrag() in my DragDetected method then I would get MouseDrag 
events on my source, but that isn't happening. Is this a bug or am I doing 
something wrong?

Please file a new JIRA and provide a small test case that demonstrates the problem.

Also, when I get my Popup moving, I'd really like it to be exactly under the 
mouse but have the Popup be MouseTransparent (or forward events to the window 

You could use the TRANSPARENT style for your popup window and paint a transparent hole (alpha == 0) in its center (or wherever you need it), and keep the popup positioned so that the mouse pointer is located above the hole. Mouse events always pass through transparent pixels. This way mouse events will get delivered to a window below the popup window in the z-order, while the popup window itself can float above it following the mouse cursor.
