Using autocomplete="off" on a password input is having this effect on the whole form not just the password field.

This wasn't the case in Safari 5.

Even adding autocomplete="on" to other fields in not working.

<form name="login" method="post" action="login.html" >
E-mail<br/>
<input name="email" type="text" ><br/>
Password<br/>
<input name="password" type="password" autocomplete="off" >
</form>
