Windows 7 Dual monitor is no longer locking mouse in fullscreen mode

It seems like you are experiencing an issue with the mouse cursor behaving differently across your dual monitors setup in Windows 7. If you want to restore the full screen mouse lock without relying on third-party software, here are some steps you can try: 1. Check Mouse Settings in Control Panel: - Go to the Control Panel. - Click on "Hardware and Sound," then "Mouse." - In the Mouse Properties window, navigate to the Pointer Options tab. - Make sure that the "Enhance pointer precision" option is unchecked. - Also, ensure that the "Snap To" option is unchecked. - Click Apply and then OK to confirm the changes. 2. Monitor Alignment and Resolution: - Verify that your dual monitors are correctly aligned in the Display Settings. - Ensure that both monitors are set to the same resolution to avoid any issues with mouse movement. 3. Graphics Card Settings: - Access the NVIDIA Control Panel (since you have a GeForce GT 440) by right-clicking on the desktop. - Under the "Display" category, check for any settings related to multiple displays and mouse behavior. - Look for options that might affect mouse behavior across multiple screens. 4. Keyboard Shortcut: - Pressing the Windows key + P can help you toggle between different display modes, which may have an impact on mouse behavior. 5. Windows Updates: - Although you mentioned that updates were installed, it's worth ensuring that all Windows updates are up to date. Some updates can potentially address such issues. 6. Restart the System: - Sometimes, a simple restart can resolve minor system glitches. Reboot your system to see if the mouse behavior returns to normal. If after trying these steps, the issue persists, it might be helpful to provide more details or try adjusting additional settings in the Windows Control Panel or NVIDIA Control Panel related to dual monitors and mouse behavior. Feel free to provide more information if needed or if you encounter any specific error messages or behaviors.
