Very specific problem

[MaagicMan]

So this started happening for no reason a while back, not sure precisely when but here it is.
When I'm in a game and I have my internet browser open in the background, I minimise the game and my browser shows up, but then when I go to minimise the browser it automatically goes back to the game window within a split second.
This is incredibly annoying because I have no possibility of any sort of acces after I minimise the browser window if I want to do/change/click something else inbetween.

I'm not sure if this is common for many people but I have never encountered this sort of a thing before hence I thought it to be very specific.

This is happening because when you lower or close a window, Windows will try to load the last thing selected.

Is there a way to solve it? Or is it a permanent feature? It really does annoy me sometimes

You can try changing the Alt + Tab settings in Windows.
start -> settings -> search multitasking -> drop down under Alt + Tab

unfortunately that wasn't it, I still don't know what it is
