BigBox should wait for the relevant process to end rather than wait for a window to close before re-enabling itself

[Migue]

LaunchBox version: 11.11

Windows version: Windows 10 build 21364

‌

ISSUE: When BigBox launches an emulator it shows the LOADING screen and then sets itself to a black screen and mutes itself. It should stay like this until the emulator closes and then show the GAME OVER screen. However if the emulator (RetroArch in this case) closes and opens its window (but the process never ended), such as some options or even switching between fullscreen and windowed with F key, will cause BigBox to prematurely show the GAME OVER screen and re-enable itself blasting the video preview while RetroArch is still running.

‌

STEPS TO REPRODUCE: Launch an RetroArch emulated game from BigBox. Then press F on RetroArch to toggle windowed/fullscreen mode. BigBox will think the game has ended.

‌

POSSIBLE SOLUTION: Wait until retroarch exe (or whatever exe) has ended to determine whether the game has been closed.
