i've made a simple tab switcher in my site, it work's like it has to; the issue is that when you scroll the page, and than try to change the visible tab, the page moves for (to me) no reason!

if you want to take a look just click:

http://800.omnigrafica.it

here's the javascript:

2. $(document).ready(function () {
4. $('#zona1 .sez.active').fadeIn(0);
5. 
   
6. $('#schede li span.centro').click(function(){
8. var sezione = $(this).attr('id')
10. if ($(this).is ('.active')) { donothing }
12. else{
14. $('#schede li span.active').removeClass('active').parent().removeClass('active');
16. $(this).siblings().addClass('active').end().parent().addClass('active').end().addClass('active');
18. $('#zona1>div.active').fadeOut(150,                         function(){$(sezione).fadeIn(800).addClass('active')}).removeClass('active')
19. }
20. });
21. });

by the way, i really don't remember where, but i guess i saw the "donothing" statement used like i've used in my script. Thanks to firebug i know it's an error, i've searched the "donothing" function, i've fount the noop() one; i cant make it work!!!

if you can put me in the right direction will be appreciated! ;)
