Go to your publish settings and select HTML as an output type. Under the HTML select the window mode Dropdown – > transparent windowless. This will publish your SWF with a transparent BG. If you want the code, crack the HTML and check out the <PARAM> tags in the embeded file for the window mode param. Something else worth checking out is your actionscript dropdown under Objects > Movie > Stage there;s some interesting properties in there too.
hope that helps you along :hat:
