The Redirect Screens are the pages you see when you have made an action such as saving your Post and then it shows you some highlighted Topics with an option to continue (See example below). Previously there would be an automatic count down and then the page would load automatically, but this has been removed and replaced with a static button that you must press. This was done as the code did not work across all browsers as well as gives a chance for Mobile users to see the columns.
Yes, I was seeing the countdown go into a loop after going to '1', and never moving past the redirect. I didn't bother worrying about it, as I've been in IT for decades and it wasn't a big deal. Thanks for the alternate! :).
