Minecraft takes control of the mouse

[IgorB2004]

When playing Minecraft in fullscreen, if another application takes focus, Minecraft "minimizes" but still has control of my mouse. My keyboard works fine, applications keep running, and I can even move my mouse, but mouse clicks don't register. I can move to other windows clicking Alt+Tab, but i can only use my keyboard in them.
I have no problem playing Minecraft and when I close it the problem disappears, but i want to use other applications during playing Minecraft ( like Browser or Discord ).
I would be greatful for your help.
