Nicholas C. Zakas writes an interesting article in Web Reference on some of the extended drag and drop “events” built in functionality & behaviour of Internet Explorer version 5.0.
Images and text for example can be selected and dragged when the user pushes the mouse button and begins moving the cursor. There is variations between IE 4.0 & IE 5.0. IE 5.5 for Windows only, Microsoft went one step further and added the dragDrop() method.
It is important to know that this functionality is available and possible, but considerations of users with other browsers and platforms is important.
