One can only imagine what some well crafted Pr0n will do to it.  Possibly send it into a tizzy of 
pop-ups and spam as the world has never seen.  What, oh, that's right, it already does just by 
going to msn.com.

In case anyone missed it, the latest hack causes a stack overflow in
IE 5 with a well crafted bitmap. Which of course make LookOut susceptible,
too. It seems they used an unsigned integer and feed that into a signed
integer, thus allowing the possibility to send a very large number (> 2^31) 
that is then interpreted as a negative and thus trashing the stack. 
Whoo hoo.
