Can't Read HTML

[John Hammack <johnhammack earthlink net>]

Problem:  Nautilus 1.0.0 cannot read HTML, it displays HTML source text 
in most cases.
Background:  Updated Debian with 3.0r2, 7 CD set.  I probably made some 
wrong selections because I am not getting all the functionality I had 
before.  I am trying to get it back one step at a time.  "uname -a " =  
Linux <hostname> 2.4.14 #2 <date> i686 unknown.  Re-ran "dselect" to 
get, Install, and Config  all dependent and all suggested files/pkgs. 
Then again ran "dpkg-reconfigure".  
Example:  In Nautilus, Select> Help > Nautilus Manual I get source 
(text) for HTML.  Left Panel is garbbled.  If I Select > Quick Reference 
I get source (text) for HTML again.  But the left panes has options, 
"Open with Lynx"  (which works), and "Open with...."  If I Select "Open 
with..."  It has a pop up box for other selections one of which is  
Mozilla.  In this case the Mozilla options works.   If I try to open any 
doc-HTML file Nautilus will not open it or give me the option to select 
Mozilla.  
I would like to get:   Nautilus to automatically open the HTML files as 
I originally had.   I have no problems going to the documentation to get 
the answer but I haven't found the page yet.  Help appreciated.  John
