Although a similar problem was initially reported by testers in Windows 10 April 2018 Update , a bug that caused the taskbar context menu to display an exception still exists in Windows 10 November 2019 Update (version 1909). The problem is that when you right-click an icon in the system taskbar, the taskbar obscures a portion of the context menu so that you can’t click the option at the bottom.
This way, if the option at the bottom of the context menu is Exit, this means that the context menu displayed below the taskbar cannot exit the application with normal mouse action.
This error occurs from time to time in various applications, indicating that it is not related to a particular application, but rather to the way the system tray icon is displayed in the context of the menu. However, for certain applications, such as Pidgin Instant Messenger, it occurs more frequently.
Interestingly, this error dates back to the Windows XP era. Windows users with microsoft community forums say the error/feature is certainly nothing new, at least in the Windows XP era. However, the solution is to try something out: after encountering the problem, the user needs to click outside the context menu and right-click the application icon in the system taskbar again to have a chance to resolve the problem.
