'** This Section Contains Drag Amd Drop Routines For Use With A Table And An Absolute DIV.
'** Notes: The mousedown, mouseover, and mouseup events should be set on the Table and
'**   never the entire document. But that also means the absolute pos div must have a lower
'**   zIndex (placing that layer under the table) or never get in the way of the mouse.
'**   Choice 1: Set the table in a relative pos div and set div's zIndex in code to 1
'**   Choice 2: Keep the absolute div out from under the mouse. (ex: Add 1 to it's Left or
'**           subtract 1 from it's top) [intLeft = 5; currently does this]
