CS4 AS2 HTML : need swf that is placed in div to resize with browser window

hey folks. i have searched for a long time and have tried many ways, but have yet to come up with a solution.

what i have:

i have created a simple slideshow in CS4 AS2 flash. i have placed the swf in my HTML page inside a div. it will be the background to my HTML index page and i need it to fill the entire browser window as well as resize proportionately when the browser window is resized.

does anyone know how to do this? any solid leads to send me to?

would appreciate any help.
