Does Safari support "cover" value of background-size property for CSS?

Question

I'm a web developer.  I've run into a Safari issue while coding up a new portfolio site.  I was using an older version of Safari that came with my MacBookPro with leopard, where in my css the old Safari was recognizing and properly implementing the value "cover" for the property background-size.
body {
-webkit-background-size: cover;
I recently upgraded to Snow Leopard and I assume my Safari was upgraded too, because now the website I'm building does not look correct in the current version of Safari.  Safari is not letting the "cover" value fill the browser window completely as it should.  Instead Safari will only allow the image to fill the background so long as the width and heighth values are lower than the actual size of my background image.  Once the browser size exceeds either the width or heighth size of my bg image, Safari shows nothing (empty space filled with bg color) beyond the image size.  The current version of Safari is 4.0.4.
I want the image to fill the background of the browser window regardless of the browser window resizing in any direction while maintaining the proper aspect ratio, so overflow of image height is generally hidden.
You can see the site I'm building here, mikepriebe.ca.  It should look fine in Chrome and Firefox.  In Safari you should see what appears to be a large uneven border around the background photo.
Any thoughts or tips on how to fix this or work around this?

Thanks Roger. Although I'll still need to solve the issue for those viewers using the older versions of Safari, even if the property value is executing correctly in the latest version of Safari.
