I have been trying to fix a problem /bugg in flex for the past 2 hours and havent found any solution yet. It looks like AS in my imported SWF files to flex are not executing. The reason? I really dont know. It also looks like swf file imported into flex through the loader use time tweening(setInterval) instead of frame tweening (onEnterFrame) I will post my solution to this problem hopefully in 1 hour.
