Sometimes, things may get out of hand and you may need to close a project. To do so, click the File menu and click Close, or click the small X in the top right-hand corner of the Project window.

Project is really smart. If you haven’t saved your file when you close Project, Project will ask you if you want to do so.

Clicking Yes will open the Save dialog (or update a saved file). Clicking No will discard all the changes that you made since you last saved it, and clicking Cancel will return you to the project.
