Linda,

I have the Surface Pro 4 and with the keyboard attached, I don't see this issue - the bottom left, bottom center and bottom right all trigger correctly when I tap them or click them with the touchpad mouse on the keyboard attachment. . I'm not sure why you are seeing a difference in behavior with the Surface Book 3, but that is very unusual. Is your device set for tablet mode or desktop mode?

Thanks,
Mike

Mike,

Most of the time I use Surface Book 3 as a desktop/laptop computer, and I use the mouse.  (I hope to use it as a tablet when I can play piano again at nursing homes.)

I searched for Settings, and clicked on Tablet Mode, and I see selection for "When I sign in" is "Use the appropriate mode for my hardware", and "When the device is automatically switches tablet mode on or off" is selected. (See attched.)

I didn't see anything in the Settings under the category "Desktop mode".

Do any other Surface Book 3 users encounter this?
