I'm on a Conversations page, and click on a thread.
Then I go back to the Conversations page, and decide I want to read the thread again.
But it's not possible to go back (actually forward) by clicking the forward arrow, pressing Alt + right arrow, etc. The only way to get back to the thread is to click the link on the Conversations page.
When I click on a forum name from the main page it takes at least 2 "Back" actions to get back to the main forum page. If I then visit a thread and do the multiple back thing to get back to the thread page, it takes 4+ "Back" actions to get back to the main forum page.
