I have played Project Zomboid for a very long time and I still have this problem. Picture this... your playing the game, having the time of your life. But then, it randomly minmized, of course the game is still going but your on your background or on a different window. Before you could get back to the game you end up getting mauled to death by Zomboids.
If anyone has any idea how to fix this or has experianced this problem, please help me. I love this game and I would love it even more if I could ressolve this Random Minimization problem that I experience.
