Steve,
OK on the master page.
You have at least two solutions. If you want to use Pub 2003 to produce your
site, then go to Tools > Options > Web tab and uncheck "Organize supporting
files in a folder". Now Publisher will produce all your files, your
index.htm file (your home page) and the other .htm files plus your images,
etc. loose and at the same level in the directory....just like Pub 2000
does. You can upload those files all to the same level in your host
directory, and I would expect that your site will work just fine.
Your second option is to keep using Pub 2000 to produce your site.
Personally I prefer Pub 2000 for web work. It uses a different html coding
engine that produces a more basic, less bloated code that is cross browser
compatible. I would ask you what is it that you were hoping to do different
with Pub 2003 that you couldn't with 2000? If it ain't broke don't fix it.
Pub 2003 does have some advantages and disadvantages so since you have both,
keep both. Just do a custom install, and install the second version in it's
own folder, and watch for the option to not overwrite the other version.
That way you can use the best features of each version.
