Actually I don't have any mouse interaction going on currently. I do have a keyboard listener to handle navigating forward.
As far as loading goes, I have a ComponentManager and a ComponentLoader class. The manager creates a ComponentLoader which uses a Loader to load the actual swf. Once it is finished loading the ComponentLoader sends the manager a reference to the Class from the swf. The manager then notifies a PresentationManager that the class has been loaded and is ready to be initialized. I had moved back to FlexBuilder2 so I haven't tried to take memory snapshots. I will do that soon though. On 11/6/07, Alex Harui <[EMAIL PROTECTED]> wrote: > > I would see if you can use the app with as little interaction as > possible.
