With the latest Title Update, some users are experiencing a Look/Spin/Stuck Key issue that interferes with user input. The temporary fix, described below, will restore Keyboard/Mouse and XInput (360) controller functionality. Support for DirectInput devices is currently limited. We apologize for the inconvenience and appreciate your patience.
To fix the issue:
A1) Unplug any DirectInput controllers (gamepads, joysticks etc..)
A2) Reboot your computer
A3) Launch GTA IV
If the issue persists, the following instructions are provided as a guide to assist you in deleting the conflicting DirectInput drivers:
B1) Exit game

**Some users are able to reinstall the drivers for their DirectInput devices, with the device attached, and have found that it will work in game. If you do attempt to reinstall your device and the problem resurfaces, please follow steps B1-B5 again.
