Hyperlaunch process lingering with only Neogeo games

[framboisier]

Hi! I've been trying to configure a MAME only system, and integrating roms as I test them. For some reasons, everything works fine, unless I launch a NeoGeo roms. In this case, the game works, but when I come back to the Front end, no games will launch anymore, and the HyperLaunch Process is still going on. Same happens when test roms with HyperLanchu.exe: the roms works fine, but the Hyperlaunch process is never killed. I tried different things with exiting keys on both the emulator and the frontend, but for some reasons, everything works fine with non Neogeo games.  Any ideas?
