Tabbing, mimizing problem, escape screen double cursor

[bricksbricks]

When my game is minimized or tabbed out the ESC menu opens ingame.
When I tab back in or open the window I have double cursors (windows and game) and I can't click any buttons and no key inputs goes to the game.

I can tab back out and right click close the program from taskbar.

I then tab back in and can choose yes or no, if I choose no it goes back to double cursor problem. and yes quits the game obviously.

how can I fix this?
