ddsmoothmenu (1.5) jumps in IE9

[autonomatt]

1) Script Title: ddsmoothmenu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...smoothmenu.htm

3) Describe problem: This is the website we're using ddsmothmenu on. The menu works as it should in all other broswers except IE(9). On mouseover any of the menu items, the sub menu appears to move the entire page down. It looks like it moves it down the length of the sub menu, so it looks like some positioning issue in IE, but we cannot figure out why IE is doing this and it is quite hard to debug (using Firebug or similar tool) due to the interactive state.

Any pointers would be much appreciated.

Thanks
Matt

Inside ddsmoothmenu.css, make sure the last portion of the default code isn't removed:

.ddshadow{ /*shadow for NON CSS3 capable browsers*/
position: absolute;
left: 0;
top: 0;
width: 0;
height: 0;
background: silver;
}

.toplevelshadow{ /*shadow opacity for NON CSS3 capable browsers. Doesn't work in IE*/
opacity: 0.8;
}

If it isn't and the problem still persists, please post a link to the page on your site that contains the problematic script so we can check it out (the link above doesn't work).
