In my ActionScript code I am adding mouse event handlers for a Canvas object (actually a subclass I wrote). When I move the mouse over a child DisplayObject that was added to the Canvas, I receive all of the appropriate event handlers. However, when I move the mouse over an area where there are no children, the events stop getting dispatched to my code. I am verifying this using traces. I do receive a mouse out and mouse over events, and I also receive a single mouse move event immediately prior to receiving the mouse over/out events, but nothing further.
Does anybody know why the mouse events would stop when the mouse is directly on top of the Canvas object and not over any children?
