On a windows 10 Pro computer, the mouse has suddenly started to cause the background screen to be displayed. The mouse is on a slanted keyboard rest. It has worked well this way for years, but now as soon as the pointer gets close to the taskbar, the background screen covers the work program [excel or sage or word].
The mouse and keyboard are Logitech wireless. Have use a different mouse with a different radio, with the same results. Updated the drivers and the same thing is happening. Is there any relationship between the pointer coming in contact with or moving towards the task bar [any part of the task bar] and the background screen being displayed
