Is there a way to have custom cursors work on all browsers? I know how to do it for IE. I think the same script works for Netscape. But what about FF?

Also, filter: dropshadow effect.. I know how to make it work for Opera, FF, NS and IE in a heading.. (its a pain in the butt :x) But how can I do it for links and what if I wanted to do it for all my text?
