Need help with Blog Network widget

I read the whole blurb on how to get the widget and know how to install it. Only problem is...I can't get it. There isn't a "copy" box that comes up when I scroll over the widget. When I click the "Get Widget" button at the bottom of it, nothing happens. What am I doing wrong? I'm on a Mac, could that have something to do with it?

Please help me figure this out....
