Modap Popup with Drag Panel Extender in User Control

I have a user control that contains a table, two panels and two modal popups, where each panel is displayed modally.  I'm trying to add Drag Panel Extenders to each panel so they are modal and can be moved around the screen.

It is kind of working, however when the modal panel is displayed and I click on the panel to move it, the panel drops down to the bottom of the screen.  My cursor will be where the panel was originally and if I move the cursor the panel does move, but the panel is always about half a screen down below the cursor.  I think this has something to do with being in a user control?

My code is attached.  This is working in IE.

The modalpopupextender already comes with functionality to enable dragging. There is no need to add a dragpanelextender to it.

Do you have anything in your style sheet that alters the margin or position of the element that contains the modal popups? I've found this can have an adverse affect.

I attached my style sheet.  I also removed the drag extender and I am using the drag options on the modal popup extender.

.ModalHeader
{
    background-position: left top;
    color: #000000;
    border-color: #333333 #333333 #999999 #333333;
    border-style: solid;
    border-width: 1px;
    padding: 3px 10px;  
    font-weight: bold;
    background-image: url('../../../../Images/ModalPopupHeader.png');
    background-repeat: repeat;
}
 
.ModalHeader .content /* The header contents */
{
    font-weight: bold;
    
}
 
.ModalBody
{
    padding: 10px 10px 10px 10px;
    background-color: #FFFFFF;
    border-color: #333333;
    border-style: solid;
    border-width: 0px 1px;
 
}
 
.ModalBody .content
{
    float: left;
    padding-left: 22px;
    padding-bottom: 50px;
}
 
.ModalFooter
{
    border-color: #333333;
    border-style: none solid solid solid;
    border-width: 1px;
    text-align: right;
    padding-bottom: 4px;
    padding-right: 8px;
    padding-top: 4px;
    background-color: #FFFFFF;
 
}
 
.ModalFooter .content /* The footer contents */
{
   
}

I had a play about with the code you posted. It seemed to work ok as is. How is the user control placed on the containing page?

After more research we found that  there is a position absolute in our master page styles.  We are trying to get ride of that and we think that will fix the problem.  Thanks.
