Well since Patrik covered the Windows front and David took care of the Mac front they
both get a net.fame for this one... 

Netmanage has just released WebSurfer v5.0 & 5.01.1 beta for Win95 and NT systems,
support includes Tables as well as the 'smattering' of HTML3ish (ya like that word =-)
tags. The Mac product (from what I can tell anyway) doesn't support plug-ins yet. But for
all the latest info here is their site.
