Sorry, but could not edit my post to add extra info due to this problem.
Just taken me several attempts to actually access webuser forums. Finally did it by using back and forwards buttons. Other than that it keeps timing out on webuser. On other sites like supermarkets (food shop!) the page starts loading but nothing happens. The progress bar moves to almost done and then nothing happens - Doesn't time out.
I've checked my firewall and even turned it off for a few seconds but no difference - Can't be firewall then!
I've recently moved to BT broadband and my speeds have varied but I'm sure this is a separate issue as it doesn't happen on all sites.
