Thanks David,
Rizgar... I agree the post reply seems to work every time now, though having looked at that thread "Is there a website.." the last post was in fact at 00.26, and therefore at 01.08 there would not have been any new posts. Suffice to say Ctrl-Refresh is a last resort, it will fetch the page from the servre and this will always be up to date, so if nothing new appears.. you know there hasn't been any new posts.
Cheers,
Pigsy.
