I'm afraid that even with use realtive links turned on it still includes the base directory

i.e if my form with the editor is here   c:\inetpub\wwwroot\mywebsite\coolforms\formwithEditor.aspx
and i need a link to c:\inetpub\wwwroot\mywebsite\file\coolfile.doc

the editor will insert the link as \mywebsite\file\coolfile.doc      - I don't want it to include the "mywebsite" directory...

any ideas?
