   window of a different app
2) Focus one window terminal keeping the other terminal window below it
3) Press Alt+Tab

4) The other terminal window is focused

Actual behavior:
4) Other opened application is selected instead.

Low, types extended from int to long long. The code affected is the alt tab functionality.
