Editor is constantly in game mode

Hi. Two days ago, my unity editor was fine, but now, it is constantly in play mode. I reinstalled it, and t is still in game mode. Can you tell me what's wrong, o how to fix it please? THX in advance.

I'm guessing you need to add tabs.

Under Window, go to Layouts, and try those... It should fix it for you =).

You can also try pressing the SPACE bar.

This can sometimes maximimise or minimise the game/scene window and give you different preview types.
