I have been having that exact same problem, then last night after opening a few topics, it started letting me click the back button to get back to the list. Then as I got to the end of the list, it messed up again and I couldn't click back. So far today, it is working okay but I just got on. Sure hope they get the bugs worked out soon. I love the site, but it is very frustrating having all these problems. Hope yours starts to work soon too.
