masks’ alpha property has no effect, as far as i know.  
You would expect to be able to use a mask to do fading, but flash doesnt support it. another thing i tried was a donut shaped mask. It came out as a circle (the hole didnt show through).

There are other ways though. Put another copy of the background on top and fade that out instead of fading the image in.
