Simon Janes To be fair, I have similar experiences with Chrome and Firefox, so IE isn't the sole offender of "wat?" when it comes to strange behaviors.

Eric Yesterday IE opened its dev-tools inside my Chrome window on a different monitor. I could only laugh at the absurdity of it. How MS can fuck something up so much is beyond me. I have a screenshot on my work machine for keeping.

Simon Janes Needs to be a configuration, however, I can see the utility of having the dev-tools on a different monitor so you can more easily test responsive web designs.
