[TxMt] Web preview and root-relative paths

[Gianni]

In my html files I use root-relative paths such as:
<link rel="stylesheet" href="/css/screen.css" type="text/css" />

The Web Preview does not work even though the path is also relative to  
the top level of the project, I have to use paths relative to the  
current document.
<link rel="stylesheet" href="css/screen.css" type="text/css" />

Is there some way to get Web Preview to work with root-relative paths  
for html development?
