Jesse, thanks for the info on this. Knowing that there was an issue helped me to find a solution before it became a problem. I’m writing some components from scratch (well, porting some AS2 actually) so I wrote an “Invalidator” class that handles it nicely without ENTERFRAME at all. Basically my UIComponent class has an invalidate method which in turn calls Invalidator.invalidate( this ) which adds it to a queue of components to update. If it’s currently listening to Event.RENDER it adds the component and that’s it (so it will be updated with the rest in the current frame), if not it calls stage.invalidate and registers the listener. Seems to work like a charm so far, obviously if there was/is third party code that manually calls stage.invalidate that could be an issue, but it’ll just an easy find/replace away.
