Ah a slight misunderstand I think Goff/Moss. It's not all the previous posts I'm having problems with in the one reply (although they are a pain) it's the replies in general. When I look to check on new posts on a thread the ones not already read are highlighted in red which then goes to orange once read. Are you with me so far? :-)
Well that's not happening here as the red highlighted ones stay red and don't go orange, thus I'm left with dozens of the darn things in red and having to filter my way through them to find the ones I haven't read.
Clear as mud? Thought so :-)

Any idea Eds?
