To go along with what I just posted, i have tried shutting down and restarting ( I dont normally) just in case as Shaun suggested there was a cache problem. I have also deleted all browser histrory etc..
Still got problems though.
Read posts remain bold blue. Not the home screen icon though that changes to light blue after visiting the section and returning to home screen
Any reply initially appears but if I return to the thread it is not visible unless I Ctrl F5
Just found another problem. If I reply again, after a recent reply, i am taken back in to the original reply as if editing, not a new reply. Hence this new post.
