I'm trying to make a simple map application that includes the map widget. I have "Enable scroll zooming" turned on. The map in the widget doesn't respond to the mouse at all. It doesn't zoom in or out with the mouse wheel, it doesn't pan in any direction. I've tested it several times. The zoom buttons work (the + and - symbols), but that's all. Am I missing something? Shouldn't the map inside the widget pan and zoom with the mouse?
