When I close last IDEA project window, I get a question "You have background tasks running. Are you sure you want to cancel them and exit IntelliJ IDEA?" But I have no background tasks running. When I press that "star" at the bottom, I can see "There are no active background tasks". And I have no Run or Debug process running. And there are even no strange processes running, like "javaw.exe", etc. I had few IDEA windows opened. I closed all of them, except one. When I try to close this las window, it shows me that message.
