I have a Dell Inspiron 3541 with all original hardware (besides hard disk). Recently, after upgrading to Windows 10 v1709 (after 6 months of "Could not install" messages), the mouse (touchpad) freezes after using the touchscreen. It won't move until I press the Ctrl
button. When I press the key, it freezes for a few seconds, and then the mouse works again.
It never did this on Windows 10 v1511, Windows 10 v1703, or Windows 8.
I have a Synaptics touchpad.
How do I fix this issue (stop the mouse from freezing)?
