[Loading Screen returns to Big Box before launching game in MAME]

I figured it out thanks to some other posts in this forum.  I had to go into the Emulator options, startup screen, and select "Hide all windows that are not in exclusive fullscreen mode"

[Loading Screen returns to Big Box before launching game in MAME]

Hi,

I have animated menus with audio so I would like that when I select a game in Big Box, it goes to the Loading Screen, and then directly to MAME (MAME64).  However, it seems to return to Big Box after the loading screen for 1-2 seconds, complete with animation and audio, and then launches MAME.  It does this whether the loading screen is set to 1 second or significantly more.  Does anyone have suggestions on how to resolve?  Attached is a video of what I am experiencing.  Thanks!
