[jQuery] jQuery 1.3 selector :first; :first-child

[jQuery] jQuery 1.3 selector :first; :first-child


Hi all,
I have trouble in jQuery 1.3 with :first; :first-child selector.
Always it selects all "a". In version 1.2.6 it worked by suspense.
What is new or wrong?? Thx for help.
$(function(){
    $('#menu li a:first-child').remove();
});
