Howdy Alex and Everyone- I have _NO_ clue why this worked, but it did.
I, a la Cairngorm technique, made a custom URLLoaderDelegate and corresponding IURLLoaderResponder. Encapsulated all the URLLoader code and its handlers of the LoadFeedCommand amd moved it out to the delegate and responder. Actually no more than a cut and paste job with cleanup of imports etc. Now URLLoader works predictably in every case ... Truly Weird!! Because the code is essentially identical... Oh well. In the world of deadlines "working reliably" is good enough for now. -Naga --- In flexcoders@yahoogroups.com, "nagaofthesea" <nagaofthesea@...> wrote: > > Howdy Alex- > > Fired up Network Monitor.
