So far, so good...

I'm not familiar with Dreamweaver, but I know the problem in HTML.  I'll try and get hold of somebody who knows Dreamweaver to post here

What the problem is in HTML:

There are two ways to set colors in HTML pages

1. In the body tag of the HTML file.  This sets a current link color, and a visited link color, but doesn't change colors of links for mouseovers

2. Using CSS (cascading style sheets code).  These can either be in a separate file linked from your HTML code or included within the HTML code.  This does do mouseovers.

My guesses for things to check
- If there's a .css file is it in the right place - same folder as your HTML files (if you move the file, the links in the HTML code to the file must also point to the new location, I think Dreamweaver will probably handle this automatically if you use the facilities in the program to move the CSS file)
- Maybe there's an option in dreamweaver to turn off HTML 4 or DHTML or CSS (if there is, and it's turned off, then maybe this is the cause of the problem)

If you don't find one... this tells you why it's not working.  For some reason the code is not being inserted into the HTML

If you do find one, then you can see what's going on

Here's the hover links code from one my sites

       <STYLE type="text/css">
               A:link          { color:#003399; }
               A:visited       { color:#003399; }
               A:hover         { color:#ffffff; background:#003399 }
       </STYLE>

This means unvisited, and visited links are color #003399  (dark blue),  a mouse over  alink is #fffff (white text) with a #003399 (dark blue) background

I think your dreamweaver style sheets will probably be a lot more complex, but look for A: lines in it
