A long-running operation is currently in progress.
If the editor isn't responding, open the terminal that you used to start the IDE
(where you ran python editor) and stop the process by pressing Ctrl +
C.
Run python editor again, then refresh this page.
If this window keeps appearing while using the interface, try closing some files (particularly if you've just run a program for a very long time!).
Warning! The editor process is no longer responding to queries from the front end. You have likely stopped the process in the terminal.
Run python editor -nb in a terminal, then refresh / reconnect.
Remember to run python ok (to unlock or submit tests) in a separate terminal window, so that you don't have to stop the editor process.
