Why a frozen window ignores your clicks
A window can stop responding when the program is busy or stuck doing work on its main thread—the part that handles input and redraws the screen. If that thread cannot process events, the click may reach the computer but the application cannot act on it yet. Clicking again does not free the thread or fix whatever is holding it up.
What repeated clicks can do
Depending on the program and operating system, clicks made during a stall may be ignored, combined, or handled later. If they are handled later, the application can suddenly react to several inputs in a row. That may mean multiple unwanted actions, such as opening several copies of something or confirming the same command repeatedly.
The apparent lack of response is especially misleading: the screen may still show the old state even while the system is trying to catch up. More clicking adds input, not a remedy.
Give the program a chance to recover
Pause briefly and watch for signs that the window is responding again. If it remains stuck, use the operating system’s normal options for closing or restarting the application rather than continuing to click. The useful distinction is simple: a click can request an action, but it cannot make a blocked program process that request.
