go to flashkit.com for more information... ive heard theres an app that decompiles an .swf file... ive never seen/used it before... but thats bad news for your intelectual property (as code) really and can be a security risk. if its a consideration, fill you code with alot of useless data to throw anyone who might be trying to copy it. if you need to store valuable security data in a flash file, make a database call instead then you dont have to worry about the security level and you can let the system administrator deal with the security issue on his/her end. i tried exporting a flash file from poser5 once, it looked awful and i didnt spend any time trying to tweak it, i just wanted to see how it worked it.
