I originally tried removeChild(event.target) and got this error 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.display:DisplayObject.
I got the DisplayObject(param) from the help docs in Flash but like I said, that throws me an error too. I tried your suggestion of casting it as a sprite or displayobject and it gives me the same error as DisplayObject(param). I also tried created a baseContainer sprite and adding and removing everything from that but it gave me the same errors. Thanks for your help Ben, I'll keep looking and if you think of anything else please let me know.

You could create a new DisplayObject, but I don't think DisplayObject(param) does anything. I think you're either creating a new DisplayObject or creating a null object, and either way, it's not going to be a child of your mySpectrum Sprite. removeChild(event.target) should be adequate, but if target needs a little help to know what to be you can do this: removeChild(event.target as DisplayObject) or removeChild(event.target as Sprite) Again, maybe I'm wrong, but that's my understanding Bieniasz, Myles wrote: > I'm just starting to fool around with as3 and having a little fun with > computeSpectrum.
