Thanks for this reply, unfortunately, when I defined the id for my class as

#editPanelTitle {
        position:absolute;
        font-family:verdana,tahoma,helvetica;
        width:  400px;
        display:        none;
        top:50%;
        left:50%;
}

the jqmodal window appeared at the right of the screen, about 100 pixels down from the top, but definitely not vertically aligned.  When I added the "margin" property you suggested, the window did not appear at all.  No JS errors were reported.
