It's different because this new message is factually incorrect. "neosmart.net is not responding" means something completely different that what is actually happening; if you open neosmart.net in a different browser, I'd bet everything would operate as normal. What's actually happening is that IE10 isn't stable enough to handle whatever the website is doing, and IE10 stops responding. But instead of admitting that, they blame the website.

Now, this might be happening in part because the website has some bad code, but in 2011 there's absolutely no way any website should be able to crash a browser. That's just crazy. Given that the browser is crashing, that's 100% of the fault of the browser and no blame at all should go to the site.

At the very least, IE should isolate the problem to the particular tab and not crash.
