JavaScript Cursor

my page include applets so when i use "document.body.style.cursor='wait';" only for the body the cursor is getting changed to wait not for the applet.
Can we change the cursor to wait for entire page not just for the body also when i navigate from one window to another window.
*I doing this for IE7 and IE8.

note applet is java not javascript , so the applet has its own mouse handling .
