Hello JB,
Let's try using the "Dual Monitor Tool". Download it through their website: https://sourceforge.net/projects/dualmonitortoo...
- Once downloaded, run the installer.
- Click "Next".
- Check the "I accept the terms in the License Agreement" box and click "Next".
- In the "Custom Setup" step, expand "DMT".
- Click both "Wallpaper Creator" and "Screen Saver".
- For both, select "Entire feature will be unavailable".
- Click "Next" and then "Install".
- Click "Finish" when the installation is complete.
- Find the Dual Monitor Tool icon in your system tray, located on the right side of the taskbar. Double-click it.
- In the application window, under the 'Cursor' section, select "Sticky".
- Click the 'change' button next to "Lock cursor onto the screen".
- Check the "Enable this Hotkey" box.
- Select your preferred key combination.
- Click "OK". Click the "Close" button.
- Press the shortcut key you just set.
See if the mouse cursor remains confined to the window. Let me know if you have any other questions or need further assistance with this.
