I have been using a Logitech MX Master 2S mouse for a number of years. As I use two computers, laptop to work on and desktop for reference, I use the Logitech Flow facility which allows me to use the mouse for both computers by moving the cursor to the edge of the screen.
Yesterday something changed. When I am working in APCD the flow function will not allow the mouse to access the desktop. If I open another window to access the internet or read my emails, the flow function works as normal.
I have reinstalled the Logitech app on both devices but no change.
Can anybody think what in APCD is causing a problem when it has worked perfectly for the last few years, and more importantly what do I do to correct it?
