On 2 different Acer touchscreen laptops (Windows 10 and Windows 11) in the Fantasy Player:
After a time… somewhere between 5-20 minutes or so, the trackpad stops working to click on a sound to play or change the scene. The touchscreen continues to function.
The trackpad still has normal function to move the mouse… Tapping the pad or clicking the pad shows the brief animation that something was clicked on but the sound is not played. Using the touchscreen still works.
Restarting the application makes the trackpad work again for a time.
