If I put a YUI menu bar in the body it works perfectly. However if I use it inside of a Panel it shows up without the proper background. It is larger than it should be. Other than the default sam skin I'm using only the following css. .windowbody is the class of the panel.
<style type="text/css">
body {
margin: 0;
}
.windowbody {
overflow: auto;
padding: 0;
}
.windowbody div {
padding: 0;
margin: 0;
}
</style>
