It is a bit confusing usually Dreamweaver opens a new html file as below :  
\<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”  
“[http://www.w3.org/TR/html4/loose.dtd](http://www.w3.org/TR/html4/loose.dtd)”\>

Whenever I use this doctype and try to run some jscripts , I notice that some don´t work , and as soon as doctype lines are wiped out then it works fine ;

I´ve tested the code on ie6 , opera , firefox , netscape 8.1 without doctype lines and all ran very well ;

so why to employ something that is recommendable but so nagging ?
