Most of that is generated when you publish HTML from Flash, but there are two parts that you need to look at:
<param name="wmode" value="transparent">
and
wmode="transparent" inside the <embed src=”etc.”> tag.
wmode is an optional parameter in Internet Explorer 4.0 and higher, that allows you to take advantage of the layering, absolute positioning, and transparent movie features. When you add the parameter tag for wmode and edit it into your embed src tag (it must be in both), it lets you set all non-object areas of the Flash movie to transparent, opaque, or window. The latter creates a separate rectangular window.
