drag and drop

[wolverine8_2]

Il problema: se definisco un <object data="xxxx.pdf" width="580" height="310">

</object>

quindi creo un pdf perché riesco a fare il drag and drop del testo del pdf solo con il plugin di IE mentre con firefox e chrome non va?
bisogna settare alcuni parametri?
grazie

A number of events are used which are fired during various stages of the drag and drop operation. In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object.
