Forum page does not respect Back Button in Safari

I have noticed that when I view a Post and then hit the Back button, I am taken back to the last page I viewed before the forums.

I then have to hit the forward button to get back to the forums.

Grrr and now it is on mine. I should have added it does this inconsistently.
