I'm a new user. I'm trying to handle IOErrorEvent in my
script. I got "The class or interface 'flash.events.IOErrorEvent'
could not be loaded." when publishing to swf. I do have import
flash.events.IOErrorEvent in my code. I'm using Flash 8
professional. Do I need to take any steps to import/install any
extensions to use flash.events.IOErrorEvent? The code is attached.
