Just load the scene and press the Render button on the top toolbar. That uses the "default" renderer (yes, it's the Full Render).
As for your problem of not being able to see the full text of the OS choices, that sounds like an example of an Internet Explorer browser issue, rather than a problem with the site. IE does not expand dropdown boxes to show full text, unlike pretty much every other browser around - Firefox, Chrome, Opera, Safari...
