When a program does not respond to your clicks, its window does not come to the foreground, maximizes or minimizes and you see (not responding) in its title bar, then that program has frozen. All you have to do is terminate that program. If a program becomes frozen and does not respond, you can kill / terminate it using Task manager. This article shows you how.
- When the Task Manager appears, select the Applications tab.
- Click on the End Task button.
- When prompted, confirm that you want to close that program.
