Thanks for the reply CyberStalker but I don't think it puts an answer to the question in hand. I have ZoneAlarm loaded on my system, and what concerns me is that Lw doesn't seem to recognise it as being there.

The icon that I'm talking about is next to the connection rate, and looks to me like a blue globe.

I'm used to ZA popping up at regular intervals. Although often annoying, the reason is usually clear to see. More to the point, on this occasion, was the fact that it didn't pop up when the new version of Lw was run for the first time.

Is there a member of the Lw team reading here, who can tell me what Lw is looking for to identify the presence of a firewall?

Thanks for any help.
