I decided that I should start posting some of the little niggles that I come across everyday, and the solutions that I’ve found, so that other people can find them somewhat easier than I may have (although that means years of PHP problems have been lost in the mists of time!)

addFrameScript is an undocumented method (does not appear in the ActionScript Language Reference) that allows you to *something *something as explained well at troyworks, AS3: MovieClip.addFrameScript

Essentially if you have a Document Class (if using external ActionScript files as opposed to Timeline scripting) that extends Sprite instead of MovieClip, you won’t be able to use Timeline scripting if *something *something

(I will figure this out properly later, but I’m at work now!)
