context menu Opera

Hi,

I'm trying to block the context menu on Opera, Epiphany and Konqueror.

At this moment I'm using

$(document).bind("contextmenu", function(e) { return false; });

Works fine on FF, IE's and Safari, but does not work or return response on Opera, Epiphany and Konqueror.

Anyone got a clue how to work this out ?

Thanks in advance.
