[jQuery] i think i fix some bug

i think i fix some bug,now it can work well in ie,bug in ff still has
some bug when ff window's width is too small.
see here
// bind key and mouse events
bind(1, el, opts);
if (full) {
pageBlock = lyr3[0];
pageBlockEls = $(':input:enabled:visible',pageBlock);
if (opts.focusInput)
setTimeout(focus, 20);
}
else {
center(lyr3[0], opts.centerX, opts.centerY);
    }
    //fix center: use Alexandre Magno's Center Plugin ,I added
    lyr3.center({vertical:false});
    //fix blockPage cann't full over whole page when the ie window's
width is too small, I add
    $(window).resize(function(){
        lyr1.width( $("body").width() );
        lyr2.width( $("body").width() );
    });
};
// remove the block
function remove(el, opts) {
