vsync - Thanks for the feedback; We have made massive improvements to the developer tools we ship with IE. Please take a minute to download & install the latest Platform Preview from here - http://ie.microsoft.com/testdrive/ - and give it a whirl. If you hit the F12 key, you should see the developer tools show up, and you will be able to see the tons of improvements we have made since IE8.

If you have any suggestions or comments, please reply back. There are many open channels of communication, e.g. the IEBlog, Connect, etc. but as an FYI, I will also be looking at responses in here, within news.yc
