Alpha coefficients not working in Simulator

I realise that the latest build has fixed the Alpha Coefficients on all devices, so you can fade Actives in and out smoothly. However, when running on the simulator, they're either on or off. It's a minor thing, but I use the Simulator for recording video to upload to YouTube. You can see the effect here when Stars are collected: http://www.youtube.com/watch?v=lPUEqLeeRiM

It would be nice to get this fixed - otherwise I'll have to start videoing off the devices themselves (past experience has not been good, with lots of reflections and blurriness - any tips are much appreciated!). I'm running the simulator 4.3 (238.2) that comes with XCode 4.0.2 Build 4A2002a on Snow Leopard 10.6.8 on a 3 year old White MacBook
with 2Gb main memory and NVIDIA GeForce 9400M graphics (in case it helps!)

Thanks!

Update - I also tried the simulator with Andos' rgbaTester and the RGB coefficients don't work either. Here's a screenshot (The Cyan Active on the right should be Grey like the box on the left) :

Sounds like the build-cache for the simulator is still using the old files from before the update.
Note that when you clean your build-cache you only do it for the currently active build setting.

Andos, you're a Star! That works perfectly (I feel a bit foolish for not figuring it out myself!)
Well done!
