For the past 2 days every new AS3 file I try to create crashes Flash on every attempt at a save AFTER the initial save. All was fine for months for a couple of projects we are working on. I've reset the Flash prefs as Adobe instructs, trashed the copies of the files on this machine, run disk utility and Onyx. Nothing helps. I can't think of anything out of the ordinary that happened this week that would've caused something like this to happen. Also, I've searched since yesterday and this doesn't seem to be an issue with anyone else. My Flash 5 app is fine if I don't use external .as files or put code in the actions box.
You might try searching / posting in the Flash General forum instead of the Actionscript 3 forum.
