Wondering if anyone's seen the below behaviour with the IE11 F12 developer and if there's a fix?
OS is Windows Server 2008 SP1 with all updates applied.
Screenshot attached
I recently discovered this same problem... F12 Developer Tools grayed out.
It turns out I was trying to open the dev tools from a blank tab. IE11 apparently doesn't like that. If I navigate to a page with content (not about:blank), then the dev tools show up again, like normal.
I feel a little sheepish, but only a little. I'm use to Chrome's dev tools, and they open up fine on a blank (about:blank) page.
UPDATE
Okay, about:blank works fine in IE11. It's when I first open IE without navigating anywhere at all (just the original New Tab) that dev tools is disabled.
