Hi Kevin,

thanks for the quick response,

just a thought, do i need to open or port forward any ports on my
firewall ?

yeah, i closed down the desktop, opened up the hub, and then the
desktop. i can see events on the right hand side of the window, but
they are only echo's and a 'hub client connect'

the weather icon still contains a massive ? !!

kind regards,
