They did mention "Internet Explorer 3 or higher or any browser that can run ActiveX". I think that Netscape have announced that they will support ActiveX in their next release.

>The Help Viewer requires that Microsoft Internet Explorer (version 3.02 or later) be set up on a user's computer. (From http://msdn.microsoft.com/workshop/author/htmlhelp/distrib.asp)

>Craig's idea of a runtime would make perfect sense. I may have to abandon HTML Help because some clients (Netscape users) refuse to have IE installed just to have this type of help. Why not have a runtime DLL? Could you imagine if we had to install VFP on every machine to run our apps?
