About once a day my game will freeze completely (0 FPS) and will prevent me from tabbing out from it. If I press alt-tab the windows graphics for the alt-tab frame will show but if I select any window Arma goes back to being on top regardless. As such it is impossible to tab out or quit Arma. I've tried waiting several minutes and that doesn't help, I've tried opening the task manager to kill the process but Arma will always be on top so I can't interact with it. The only solution is hard-restart my computer.

I have however found a sort-of workaround by creating my own program which I run in the background that listens for keypresses F9+F10+F11+F12 all being pressed, and if they are pressed it will perform a kill on the arma3_x64.exe process. This will make Arma close and a window will pop up saying that Arma crashed asking me if I want to create a troubleshoot report. This report is attached.
