Absolute div in a relative div - IE problem

[kujie]

I've got an absolutely positioned div inside a relatively positioned div, but in IE the child div is breaking out of the parent and uses the body as its parent. There's a width and a height on the parent div, and all divs above the parent have position:relative and a width. It behaves as expected in FF and Safari.

The page is using XHTML 1.0 Trans and is running in Standards mode.

Thanks for any help!

<div id="container">
 <div id="wrapper">
 <div id="menu">
 (inside is Macromedia's mm_menu, which is what is jumping out of the parent div, but is absolutely positioned)
 </div>
 </div>
</div>

#container {
margin-left: auto;
margin-right: auto;
width: 761px;
background-color:#ffffff;
position:relative;
}

#wrapper {
width:577px;
float:right;
text-align:left;
position:relative;
}

#menu {
position:relative;
width:538px;
height:30px;
text-align:left;
padding-left:10px;
padding-right:29px;
background-color:#318b4d;
}

But what exactly is the CSS for this object - may be there is something that conflicts?!
