Hm.. I've read the article on "theinquirer" two days ago.
Unfortunately this "trick" doesn't do anything to my IE6 (on XP with latest updates).
For those for who this trick works, besides "crash" you can type anything you like i.e. "IE sucks".
The bug works for every program that uses shlwapi.dll (Outlook, Frontpage) so it isn't IE's fault, rather bug in the lib.
Anyways, Opera7.10 rulz for me.
