This is fine so far. You have to sign up first and download a small plug in but it runs
apps in a sandbox, apps you don't even have to install. After I set it up I clicked on
the green button for IE 9 beta. I do not have it installed. I was unable to move the
browser by grasping the top though, it just stayed right there.
