Sometimes a program displays an error message in a pop-up box. This is a variant of the preceding point, but I think of it as a different class of problem. As a user, there’s not much you can do except avoid whatever you did that brought the application to this point.

If a calculation is mistakenly written so it never ends, and during which Windows is not given a chance to operate, the application may become “hung” and unresponsive. The classic case of an “infinite loop” in programming is perhaps the most common example. While lengthy calculations are one semi-legitimate cause, there are many other possibilities as well. Once the response arrives, it becomes responsive once again.Īnything causing an application to stop responding to your input, or to Windows’ internal requests, can cause “Not Responding” to appear in the title bar. During that time it might well become unresponsive. If the connection is bad or the remote server is slow, the program might spend a long time waiting for a response. Once the calculation is complete, the program starts listening and responding again.Ī different example is a program trying to access something over a network (like the internet). While it’s bad design to not respond while performing lengthy calculations, it’s also allowed and legitimate. It tried to pass your request to the application, but the app isn’t listening. If, during the operation or calculation, you attempt to close the window and nothing happens, Windows might eventually add “(Not Responding)” to the title bar. There are “legitimate” reasons this can happen.įor example, if the program you’re using is doing some very long, CPU-intensive calculation, it might not respond in a timely fashion - for example, a video editing program performing some operation on a large video, or a spreadsheet performing a lengthy calculation. If the program never comes out of that state, we also call it “hung”, as in “hung up” on something. When Windows asks a program to do something like take a keystroke or close itself, and the program fails to acknowledge the request within a certain amount of time, the program is classified as “Not Responding”. If you click on the Close Program “X” on a program’s window, and the program doesn’t acknowledge it, it’s “not responding”. If you type a key and the program you’re using doesn’t take it because it’s too busy doing something else, that’s “not responding”. Windows expects a running program to “interact” with it and respond to its requests in a timely fashion. Programs are expected to respond to Windows It can also be due to errors of various sorts including a programming bug, a design error, a hardware problem, malware, and more.

This can be due to legitimate delays, as the program is busy working. “Not responding” happens when a program stops interacting with Windows properly.
