jQuery slideUp bugs after page is scrolled

[aldewan]

I'm experiencing some problems with jQuery's slideUp and slideDown functions. If you go to this sitewww.confide.re/confideand click on one of the boxes, it normally works fine, but after you scroll the page and it loads some more boxes, then the slide function bugs and does it twice for no reason, if you get what I mean. Is this something I've done wrong somewhere or is this a known bug?ThanksHere is the code:\[code\]var state = 'down';$('.overlay').click(function() { if(state == 'down') { $(this).next().slideDown(155); state = 'up'; } else { $(this).next().slideUp(150); state = 'down';}\[/code\].overlay is a transparent div on top of each of the boxes.
