And now the 2nd BACK takes me to the topic refreshed with the new message. Before it took me back to the old thread and I had to refresh to see my message added.

Sort of meh....  either way is OK.

I suspect that now you have the automatic refresh of pages, which is good.

Yea, good and bad I guess.  I never use the back button because I know how to internet.

I use the back button because it's there! 

Ban the back button John!   

Another related problem John.  Did a search and got a list of replies.  Clicked on one to read and then when I hit the back button to select another I got a page expired message.  If I hit refresh and then retry in pop up box I went back to a previous search not the one I was now on.  So I reset the automatically to search every time in internet options settings like I had it for a while yesterday and when I tried again to go back from a search reply to the list and got an expired message a refresh and retry brought me back where I wanted to go on the current search list.  Good enough, search usable, but not quite right yet I think?
