Here is an example of what I am talking about.
<html>
<body>
<div>Top</div>
<div style="height:200px; overflow:scroll">
Put CuteEditor Here
</div>
<div>Bottom</div>
</body>
</html>
If you put a CE in the middle div tag, it will force a scroll bar in that div. If your scroll is at the top and you right click, all is good. If you scroll to the bottom and right click, you will see the menu displaced from your pointer. If you had stuff above the CuteEditor inside the same DIV that it is in, this displacemenet between pointer and menu becomes extreme.
