I'm not sure how I did it, but when I right click on the page and choose Inspect Element in Google Chrome, it's taking up the entire page. I think it's supposed to be a split screen like Firebug.
Q: How do I split the Web Inspector page?
Can you drag the window down to resize, split it into its own window, or maybe it already is in its oown window? There is an option to dock it in the page.
