I've ran into a strange issue on my arcade cabinet running Windows 10. I put the AM shortcut in the startup folder in Windows so it will launch. It does launch but when you launch a game it will launch it twice, so you'll hear the game you're playing plus another instance running in the background. Once you close the game, it will jump back to the other instance of the game and you can close both. After that, it runs normally. I tried changing the select button in MAME to a different one from AM (AM button 1, MAME button 2), still have the same issue. Even more strange is if I don't have it autostart and launch it manually it works fine.
