[jQuery] Re: detecting edge cases when swapping divs

@Robert The code didn't work for me.

@Charlie I tried length=0 and length=1 and the pane always goes past
the footer div.

$(".pane .arrowdown").click(function() {
    if($(this).next().length==1) { // charlie: will return true if at
bottom, would have to test after the animation, or use length==1 if
test before animation
                $(this).css("visibility","hidden");
                return;
        } else {

    $(this).parents(".pane").slideUp("slow",function(){
                        $(this).insertAfter($(this).next()).slideDown("slow");
        });
    return false;
        }

});
