Help. DayZ standalone error?

[Elegisus]

I was just wondering if this was happening to anyone else other then me. i'd be playing DayZ and then all of a sudden it brings me out of the game on the desktop. i had not pressed any buttons on my keyboard to bring me out on desktop. i try to click on dayz to get back into my game but it doesn't let me, and i also press any key on my keyboard that might bring me back into the game. it still didn't work. i have to end up pressing ctrl-alt-delete and sign out then sign back in then reload up my game. it happens 1-3 times in a 2 hour session and is pretty annoying. Was just wondering if any of you guys know what i can do to make that stop or atleast be able to get back in my game without signing out. I really don't think it's a DayZ standalone error, but still would like to know if there is anyway to get back in game without signing out. i have windows 8 and don't tell me its because i have windows 8.
