How to change html-css cursor style in Adobe Air?

We all know how to change cursor style in  Html pages, of course using css such as,
'cursor: url("move.cur"),  move'.
But when I use it in Adobe Air, it will not show the standard  cursor style in browser, but the special ones in Adobe. For example, the  'move' cursor shows like a hand(the same with the move hand in Acrobat  Reader), not like a crosshair.
I tried to use 'url' option in CSS,  but it doesn't work in Adobe Air(I'm sure that it works in html  browsers).
I am really confused. And looking forward to your  solutions.
