gtkD: events being triggered twice

[Johnson Jones via Digitalmars-d-learn]

GtkEventBox - Enter
GtkEventBox - Enter
Down
GtkEventBox - Leave
Up
GtkEventBox - Leave
GtkEventBox - Leave
That is when I move the mouse over the event box then click then 
move out out then release.

I would expect

Enter Down Leave Up

The fact that enter and leave are not paired equally is a 
problem. Can be worked around but seems like it would be a bug.

the code is simply


ebox.addOnEnterNotify(delegate(Event e, Widget w)
{       
writeln(w.getName(), " - ", "Enter");
return true;                                                                    
});

ebox.addOnLeaveNotify((Event e, Widget w)
{                                                                       writeln(w.getName(), " 
- ", "Leave");
return true;
});
