SD and G de W, thanks for your replies, not all if which I understood! However, I tried IE and then downloaded Firefox and both of those were fine. It therefore seems that it is a Netscape problem which is not specific to any particular website.
For my 'edification' do you have any
simple instructions that would allow me to identify which bit of Netscape is at fault. It's a fairly recent happening so don't understand the cause.
Thanks again.
