Just great when you waste half an hour figuring out why you can’t get your flash to run in fullscreen mode 
To save you the time and frustration, here is why it didn’t work:
You can’t use the allowFullScreen = true and wmode = transparent together 
Somehow the flashplayer is not smart enough to simply make the background opaque when you set the player to fullscreen mode.
Lets hope they fix this in the next player update…
