There is an exception in the hide function when calling hide on a null object in IE

Line:5331 in Version 1.4.1

While looping. I added a try block to fix this issue in my version but I would suggest this be part of the final build

Set the display of the elements in a second loop

to avoid the constant reflow

try{

for ( var i = 0, l = this.length; i < l; i++ ){

this[i].style.display = "none";

}

}catch(e){}
