At the height of the browser war between Microsoft and Netscape, the competing companies released new browser versions one after another. Recently, the war has been downgraded to a minor skirmish. It’s been almost a year since Netscape released version 6 of its browser, and Microsoft is only now shipping Internet Explorer 6. Unlike Netscape 6, however (and its update, the much improved 6.1), IE 6 is not a complete overhaul. This incremental upgrade offers just enough new gizmos--including improved privacy features--to keep an IE user from switching to Netscape 6.x, but its interface remains relatively unchanged. Just about the only reason we can figure that it even deserves the full 6 version number is its release in conjunction with Windows XP. For those of you not upgrading to Windows XP, whether you run IE 5.x or Netscape 6.x, there’s no need to rush for this download
