Is this some April's Fools' joke by Microsoft?! This is more annoying than anything else, but since I came back this evening, every time I type inside the page of a browser, I get this message that says "Press ESC to leave full-screen mode." WTF is this? I never keep my browser in full screen save for YT videos and pressing ESC doesn't do anything to alleviate this. As I type this, I play with the space button, and that doesn't bring up the message, but hitting the back button or any of the letter keys does. It wasn't doing this when I used my computer this morning, and I've been gone for about nine hours.
It's telling you that you need a Mac. Full screen mode is used for video and other things. F11 is often the key used to toggle in and out of FSM. Not sure why you're seeing this, but try hitting the F11 key. If that doesn't work and the ESC is not ending the issues, see my first suggestion.
