hello it starts again, with pinball arcade, pinball fx3, and sometimes with roms from mame, it's very random. Same thing with Mgalaxy10. I am on Windows 7. Mgalaxy6.0 does not have this problem, but I have a problem displaying in vertical full screen, with 2 screens. The frontend of Mgalaxy 6 protrudes from my vertical main screen (1080x1920), I can't find any parameter to fix this problem. THANKS
