mousemove events double firing in Safari 4

mousemove events double firing in Safari 4


Using the code:
jQuery(document).ready(function(){
jQuery().mousemove(function(e){
console.log(e.pageX + ', ' + e.pageY);
});
});
I'm seeing mousemove events double firing in Safari 4, whereas in FF
they fire only once. I haven't been able to test other browsers yet.
I wanted to see if this is a known problem (couldn't find a reference
to it on google), if it's even considered a problem, and whether it's
worthy of a jQuery fix?
Cheers,
Stephen.
