My game keeps minimizing on its own when I'm on an important part of a mission, and if I minimize it the game crashes making all my progress pointless. I've somewhat taken care of this for the story by just saving it often. But the main problem is with the Lost Viking mission, it's impossible to get the achievements because it minimizes at the first boss. I'm getting so frustrated with this it could even make me stop playing Starcraft 2 altogether despite it being my most favorite game of all time. I really need help with this if you don't have a possible solution please don't reply if you have anything that could help please tell me, no sarcasm please that'd be trolling anyway but usually I just get sarcastic replies and it's annoying. Pretty sure other people may be having this problem so this could help others. -I don't use Firefox... when I looked up this issue it seemed as though people kept reffering to Firefox, well I don't use it so it can't be the problem. Again thanks in advance, I didn't post in Tech Support because I have a 2000% higher chance of getting a response here. But if it's absolutely necessary I will repost my question there, thanks.
You're not pressing any keys by accident are you? You can disable the Windows key and Alt+Tab in the Gameplay Options.
