Why we don't support Netscape
Actually, we do support Netscape. If you absolutely do not want Internet Explorer installed on your PC, you can still use Netscape to view web pages in Active Worlds. However, to do so you must separately start up Netscape and run it concurrently with Active Worlds (we do not recommend this on PCs with less than 32 megabytes of RAM.) If Netscape is running, Active Worlds will send the URLs it encounters to the Netscape browser for display. You will have to switch back and forth between Active Worlds and Netscape in order to view the web pages.
What we can't do is run Netscape inside Active Worlds the way we do with Internet Explorer. This is because the integrated web page window is implemented using ActiveX. Internet Explorer is capable of running inside other applications as an ActiveX control, while the Netscape browser is not.
