I tested this theory and I was correct, the 8bit mask doesn't work for semi-transparencies (unless I'm doing it incorrectly). I followed your example ralf and it worked great for images with 0% or 100% transparency, but not for variable transparencies (ie. tinted glass). Is this a bug with swfmill?
Regarding png size, I've been using imagemagick to resize my images and apparently have been doing it wrong all along. I have been able to get some file size improvements out of it, but I still feel I can do something here on swfmill's end to compress it even further.
