Matt, My understanding from reading the binding code is that bindings do not use a weak reference when they add an event listener, so bindings must be cleared (unwatched) in order for an object to be available for GC? Are bindings created through MXML automatically unwatched at any point? Or am I wrong about bindings using a strong reference? Thanks, Sam

Have you made sure that relevant event listeners are adding themselves with the weakRef param set to true? Sometimes in addition to removing children you may also want to try setting some references explicitly to null as that can help accelerate garbage collection. Finally, using the debug player make sure to run the GC manually just to ensure that it isn't simply a delay in recollection. There is a known issue where event listeners that are still around and should technically be GC'd might still receive event listener messages until they have been reclaimed. Matt
