Launching game in Bigbox won't hide mouse

[maxforwardspeed]

Hello, I'm running an AHK to launch a game that calls for nomousy.exe to hide the cursor. I have absolutely no issues running the game from Launchbox, but every time I launch from Bigbox the mouse cursor appears when I move the mouse. I've toggled some of the BB mouse settings and can't figure out what is overriding my nomousy specifically in Bigbox, since I'm having no issues in Launchbox with this script. Is there something I need to add to my AHK to make this not happen? 

Here's my script:

Actually, I tried the BB option to "hide mouse for all apps" and that seems to solve the problem. Although, I'm not sure yet if this will create a problem with other platforms that are lightgun games.
