For wireless mice, remove the attachment in the USB port and shut the mouse off, and then plug it back in, wait a minute, and switch it back on. Doing this could be enough to establish a new connection with Windows and make the cursor work again. If this fails to work for a wireless mouse, you can try to set up the wireless mouse as a new device.
Grand Theft Auto: Vice City > General Discussions > Topic Details. ridgedog231. Dec 25, 2020 @ 8:15pm Mouse not working The mouse won't work. Anyone know how to fix this? Just minimize the game by pressing the ‘Windows’ button on your keyboard and jump back to the game by clicking on its icon in the taskbar. The mouse should now start responding in the main menu. However, this minimization trick won’t cut it for getting your mouse to work in-game.
