i have 2 monitors. my mouse works on top screen, and i cannot see the mouse arrow on arma screen, now i can move and highlite my options such as quit and configure etc.
i move the mouse off the screen to the other monitor works fine.

now i had the same issue with planetside 2, but i was able to window the screen, then it worked fine.
i can not seem to window the Arma screen. it just wants to stay fullscreen.
just like the old DOS days..you were able togo to the game and select open in a windows..but looks like 10 wont due that..

Ok update found out how to open Arma in a window,and not full screen. So it works in that mode. But not in full screen mode
