How do i exit/close Mednafen (Not toogling fullscreen on/off)

[ModerateNOOB]

Hello there emu-crazies

I'm slowly getting the hang of Mednafen and actually went into the config. and changed the resolution to fit my screen (1920x1080), But there's is 1 thing that simply eludes me?????

How on earth do i exit the damn thing when it's in fullscreen mode???, For some very weird reason F12 dosn't shut it down (It dosn't do anything).

Everything else is set up perfectly and according the Mednafen's own tutorial F12 should be the key to exit it (Am i missing something?)

The idea is of course to start it in fullscreen next time i boot up a game (so i need to close it from fullscreen).

Or maybe there's some secret command line that will do the trick (couldn't find any)

Thanks a bunch in "gameboy" advance.

Sorry sorry, Found out what was wrong.

It's ok to close/delete my post.

I'm a little dizzy after checking  and configuring my entire collection of 2200 gba roms ( 1283 after deleting all the Japanese i couldn't find a translation for)
