On a PC you should be able to press Ctrl+ Alt + Delete and choose to run the task manager. Once that is up make sure you are viewing the tab with the running applications. You can right click on an application and choose force close to end it.
On a Mac right click on the icon for the application you wish to close and select close or "end now."
