Mac OS 10.5.6
I've noticed that when I am in Full Screen mode with a Transparent Background and I activate the Mic Expand Effect, I lose the transparent background. As soon as I turn the Mic Expand effect off, I can get the transparent background by exiting full screen and re-entering full screen.
This wouldn't be that big of a deal, except I am using Alchemy in a projection environment and exiting full screen isn't an option (harshes the mellow). As a result, I just don't use the Mic Expand. Its kind of a bummer though, because the Mic Expand is sooo cool with live music.
Here is a screen capture demonstration. Sorry about the water mark, I hope its not too distracting.
