Re: Hub problems

Thanks Kevin & Stuart for your replies.

You both hit on it with the network connection questions. When I
tried the Viewer again last night it worked straight away but then
later it didn't. I realised that the difference was that the first
time I had my network cable plugged in, the second time I was running
wirelessly. I then had a look at my network connections and found
that my wireless connection had the software firewall turned on. The
firewall has many settings, allow this allow that, so I allowed and
enabled everything but it still didn't work. So I turned it off and
now all is working fine.

BTW I'm running xp.

Thanks for your help, I think it would have taken a lot longer to
discover it was the network connection without your prompts.
