If you are using the ATLAS Drag Panel Control then you might have noticed that when you drop the panel on the screen it goes back to its original position. There is a very easy fix to this problem.
<body style="width:100%; height:100%" />
Yup! all you need to do is to make the body width and height 100% and that is it. Now, when you drop your panel is will not reset to its original position.
