FrontPage 2000 (which I have) lets you preview in either Explorer or Netscape. As for generating extra html, I don't really care. Now that I don't have to write html anymore, I don't really care what's in the background as long as my screens look like I intend them to look. But FrontPage does have some procedural idiosyncracies that are awkward and confusing, so I'm not exactly championing it. Also, the sites that are really impressive to me lately seem to use scripts and flash and other things that I have not tried yet.
