Right, because a good way to fix errors on a web page is to change your operating system and browser.

I am curious which JavaScript errors you're seeing, though, skrebbel. I don't see anything amiss in the developer console on Safari 5.1.7.

As another Opera 12 + Win7 user, there are 2 errors. A ReferenceError (undefined variable pluginlist when trying to add "Java") and a TypeError (CourseApp.Views.ChallengeMenu is not a constructor).
