Yes my main monitor is set to primary and is #1, the marquee is #2. In BB options when I choose monitor 1 in any settings it uses the marquee, if I choose monitor 2 it uses the main monitor. Even with them set that way all emulators work perfectly fine except Mame. If I just start a game, If I choose Run With->Retroarch->mame_libretro, they monitors work fine. But mame_libretro doesn't set all my controls properly and doesn't use my trackball and spinner like mame does.
