Hi Mike, I won't be posting the source of this one yet (it's a mess), but I quickly converted this Beta 2 / 3 example I did to illustrate the power of .lock().
http://www.unitzeroone.com/flex_2/mandelbrot_explorer/ It's a simple Mandelbrot explorer, it was one of my first attempts of creating a Flex component. I just polished it up so it works again, it's not finished. If you first change the settings to one of the larger ones (Either HUGE, Fraczilla or WS), then hit "draw", look at the Ms, then change the lock checkbox, hit draw again, and see the MS rise. On my duo core machine it makes about 200Ms of difference in WS size.
