SUCKS!
I just reloaded the OS on my laptop and dloaded all the updates and IE8 was one of 'em.
It has crashed everytime so far - not sure if it was the site causing a lag/problem or what.
It happened once when I had two tabs of YT open and then tried to close all tabs - just sat there and then said "Not Responding."
I'm a die hard PC guy and my brother is a manager for Microsoft but dang - I'm about to run to the Mac store and get me a MacBook and call it a day.
I'm hoping a new computer combined with Windows 7 will help IE8 perform better but we'll see....
