Which version of Windows you use brother?
I use windows 10 x64.
I will explain this to you. minimize/maximize depends upon the
resolution/game_window of VC-MP. If you check Hazard's video, you'll notice clearly that He is playing with
game_windowed 0 instead of
1. It usually happens; when you rewindow your PC, your game_windowed mode is set to 0 instead of 1. So player's usually do
/setconfig game_windowed 1
(I'm pretty much sure you know about this)
the conclusion: when you have set your vc-mp game_windowed mode to 1, it will not minimize. Instead, just pop up a dialog box and revoke your controls from VC-MP. In this situation, you are not immune. Any player can hit/damage/kill you.
When you have game_windowed mode NOT 1, ANY popup will minimize the game. Because of the configuration settings. In this case, the game is minimized and you're immune till you maximize your game screen back.
I hope it's clear.
