Why is page back not working right?

[Myself]

If I go to my subscriptions or recent posts, I like to look through things and go back to the list if a certain post doesn't interest me. On this updated site, the page back kicks me straight back to the main forums page. Then I have to re-open subscriptions or recent posts........every single time. What's up with that?

Did somebody change something? All of a sudden this morning it seems to go back only one page as it should.

Now this evening......not workling again.....
