I'm not sure what's going on, there seems to be some script error now such that whenever I go to Setting -> List (or other tabs), the page is redirected to the Overview page. I am pretty sure it's a script problem, because once I get to the List Setting, I can hit STOP and make the page stop running, then I can add new lists.

I uninstalled Google Gears, using IE7, no weird add-ons.

Additionally, there is another bug with your HTTPS (SSL) setup, usually this is caused by linking to images without the proper https URL, thus the browser will pop-up an warning window every time.

I would consider these 2 issues to be MAJOR defects, especially since you just went RTM a couple days ago. Please look into it, thanks.
