Drag events following pressed events.

You might have a look to PopupWindow.consumeAutoHidingEvents property.

By default, it’s true so I think it’s why PopupWindow consumes the MOUSE_PRESSED event.
If you turn it to false, MOUSE_PRESSED event should flow up and reach your background object.

> I'm confused about how pressed and dragged events are related in JavaFX. My initial assumption was that MOUSE_PRESSED events would *always* precede MOUSE_DRAGGED events. That is, you would never find a case where a MOUSE_DRAGGED event fired on a node and a MOUSE_PRESSED event had not fired.

If I drag on a background node, a MOUSE_DRAGGED handler will fire but a MOUSE_PRESSED handler will not. Like the MOUSE_PRESSED event is being consumed in the process of hiding the popup, or something. I observed this behaviour in both JavaFX 7 and 8.
