Problem to determine NetScape browser version

Hi, I'm trying to determins users' NetScape browser version and based on that, I need to display different messages. Is it possible for me to tell if a user has NetScape 7.0 or 7.1? I tested with following javascript,
alert("broweserversion: " + navigator.appVersion);
On both 7.0 and 7.1, I got the same alert message like, "browserversion: 5.0 (Windows, en-US)". So I can not tell the difference. And it is not even showing me the correct version.
Is there another way I can accomplish this?
Thanks.

If you want to do browser sniffing then here is the site for you to look at...

There are tons of links for you to look at here that show you how to detect the difference between mjor and minor versions.

Cool! I found what I need from that site. Many thanks!

I had to use that site to get Opera versions correctly since it can hide under other browsers.
