When I select "Run" to test a solution (or use Alt+Shift+F10), IntelliJ runs a past solution. I have selected "Edit Configuration" in Run dropdown, and removed configurations from past class builds so it can rebuild the currently active class, but it still pulls up an old file from a past lesson. I dont know enough about IntelliJ to troubleshoot this on my own. Please help so I dont have to keep copying my code to the browser IDE to test and submit code!
