Go read this interview with Matt Knox, who wrote adware for Direct Revenue for a while. Even if you aren't a computer geek. Just go read it. So you have some idea what you're up against if you're running Windows and using IE and trying to keep from getting 0wn3d. Because Windows is working against you.
So Microsoft's Hotmail service and Google's Chrome browser have had this compatibility problem. Google just pushed out a minor patch to Chrome to make it fake a Safari useragent string when talking to *.mail.live.com, which turns out to be all that's necessary to fix the problem.
But what's funny is the resulting pissing match...
[Google] We got tired of waiting for MS to fix their web page, so we fixed the BROWSER because that was quicker. Which is so wrong.
[Microsoft] Hey! We have a lot of users on Hotmail. It's a major web service. It takes time to roll out a change to a service this big.
[Google] Uh ... dude. We, like, have this web site, you know. We update it all the time. You might have heard of it...?
