Adobe Flash (SWF) doesn't display

This isn't a big deal, but I notice on the Sandbox test server my Adobe Flash SWF doesn't render on the ASPX page (it is fine on the production servers.)

If you want to see an example, go to:

http://user439.netfx4lab.discountasp.net/access342.aspx

The page is blank (check it against the production server www.access342.com)

If you right-click you will see some weird choices in the context menu.

(It works fine locally with Silverlight 4 RC.)

This happens from all computers...MAC or PC and all browsers (IE, Opera, Firefox, Google Chrome, Safari, Sea Monkey.)
