When players start the game the mouse freezes at the first window. in order to clic the play button you have to right clic very carefully repeatedly to move the mouse to the button. When you get to the play screen it is the same. once in the game everything is fine until you open the menu. At that point the mouse freezes again and you have to use the right clic to move the cursor to your choice. I and others have uninstalled and reinstalled the game several times. My mouse worked fine until the last update. I have checked my file integrity on steam and the game is fine. I can play the old dayz , arma3, and all COD games with no problem.
