Once you’re ready to take a break, log out from the Notebook Aspect to release computational resources to others. Don’t worry, all you opened notebook tabs are saved. When you log in later, you can pick right up.
The best way to log out is by clicking on File → Save All, Exit, and Log Out. This will make sure all your open notebooks and text files are saved before logging out.
If you don’t want to save open notebooks, click on File → Exit and Log Out Without Saving instead.
When you log out from the File menu, a message pops up titled Waiting for confirmation. Click OK and wait. Dismiss any error messages (like Server Connection Error).
Once you see a message titled Shutdown complete, you can close the browser tab or window.
