scrollbar in FireFox

[itgoes]

I have css code that automatically displays content with a scroll bar only wile the user is over the object:

#popitmenu{
position: absolute;
background-color: #CCCCCC;
border:1px solid black;
font: normal 12px Verdana;
line-height: 18px;
height: 200px;
z-index: 100;
overflow:scroll;
overflow:auto;

everything works fine in IE6 but in firefox the scrollbar itself remains (even thought the content goes away.)

what is the Firefox solution?

Why do you have two settings?

overflow:scroll;
overflow:auto;


Without seeing the rest of your page, it is hard to tell. I'm assuming that this "popup" happens either on hover or through javascript.....
