If you run the example shown here:

You will observe that the map can not be repositioned by dragging the mouse nor can it be zoomed by double clicking on the map with the mouse or using the scroll wheel. Further, if you extend the example to add Markers to the map, they will not receive any mouse input either. This functionality used to work in JavaFX 2.0 and 2.1.

Note: you can still click on the controls to reposition and move the map, it is just the map itself, along with any overlays, that no longer receive mouse input in version 2.2.
