As for more detailed reproduction steps: Game is open in left monitor. I hit tab to open inventory and produce the mouse pointer. I then slide it to the right of the edge of the screen of the first monitor to my secondary monitor where I have usually some chrome pages open. When I select chrome the game closes and after I have finished using the secondary monitor I select the windows task bar DayZ application pin to reopen the game taking me to where I was when I clicked out. 6/10 times this resulted in no curser/pointer available on my dayz inventory screen and I would have to force command the program to shut down and then restart in order to get the cursor to appear again.

Is that sufficient?

Would you like my in game settings or what is actually in my Windows settings?
