With Netscape v4.6 and higher you need to uninstall Netscape Smartdownload. Then click on Netscape Smartdownload and click on remove. This means that the site to which you are trying to connect to is not sending you back any information. Just try reconnecting to the site. I am using a cable modem with Netscape as my browser.
Cable modems use a proxy server to connect to the Internet.
You must first download the updated version of KidProof from the following link kidproof.exe . You need to set the proxy server settings in KidProof. They are located on the Internet Tab under the proxy server sub tab. You must also set the proxy server settings for Internet Explorer for the filtering to work with Netscape. You can setup the settings by opening Internet Explorer and clicking on view and then clicking on Internet Options.
