The Lucida font stack is.font-family-lucida {font-family: "Lucida Grande",Helvetica,Verdana,sans-serif;}
The problem is that on a Windows machine (either XP, Vista or 7) Helvetica is automatically substituted with Arial, so Verdana is never used. Thus the Lucida font stack is equivalent to the Helvetica font stack.
The correct Lucida font stack would be:.font-family-lucida {font-family: "Lucida Grande",Verdana,Helvetica, sans-serif;}
Please fix.
