Fairly straight forward, 99/100 times that I have attempted to alt+tab out to check a map, or whatever I need to minimize for, upon returning to the game my mouse cursor is invisible, I can do somethings but it makes the inventory menu impossible to use and even exiting the game requires alt+F4, which is the only way to get it back.

The only application I can think MAY be interfering with it and causing it beyond Dayz itself is Overwolf, but Overwolf is a pretty common teamspeak application so I would think it would have been reported by now.
