I admit it, I'm using IE11. I kind of like it, even. One problem: in Gmail, I get an alert that I'm using compatibility view, even though I'm pretty sure I am not. I go to Tools -> Compatibility View Options and there's a list of sites that I've enabled CV for (and there's just one there, something I use for work on occasion) and Google/Gmail/etc are not listed. But Gmail is pretty sure I've got it turned on.
Is there a way to go out of my way to ensure that a site is NOT using Compatibility View? I guess it isn't hurting anything other than the annoying alert at the top of the screen.
