If you're having issues with it, you should report them to the Help Desk Honestly I haven't had problems with it since it was in beta, so I know it's limited to some browsers and setups. Any information you can give them helps them fix the problem.
I just submitted something and everything worked fine, I think you need to be more specific about what issues you have with the new page and what glitch you experience and report the bugs, just saying change it back it's not really a good suggestion.
Er, well actually this is kind of embarrassing...I've been refreshing, force-quitting, turning my airport off, etc for nearly 10 minutes just so the "change main file" thing would actually load; and IT finally just did like 2 seconds after I posted this.
Either way, it shouldn't take that much effort to get it to load. What browser are you using? Some of them are having more issues with the new system than others.
