HyperSpin/RocketLauncher appears to be hiding keypresses from MAME emulator

I have a cab that's running hyperspin with a miniIPAC & a USB keyboard and everything was working just fine.

I decided to upgrade to Mame 243 this week. I updated mame successfully and everything appear to be working okay.

I started updating the keyboard configurations in mame & HyperSpin to get the controls just right
Unfortunately, after I was done I noticed a problem that now when I launch any emulator (SNES/MAME/etc) from hyperspin - keys presses are sporadically not registering within the emulator that's running.

When I either
1. Use Windows Task Manager to kill the Hyperspin process and tab back into the emulator - all keypresses register
2. Disconnect the USB Keyboard - all keypresses register

I think I have mis-configured something in HyperSpin/RocketLauncher that is causing a conflict with the USB Keyboard & miniIPAC that effectively 'hides' keypresses from the emulators. I remember changing multiple cfg/ini files while upgrading to MAME 0.243 but I cant find the problem.

Would anybody have ideas on how I can debug/fix this issue?

Here are some logs file that I hope will help

So I found a solution to my problem, just putting it here in case anybody else has the same issue.

My solution was in RocketLauncherUI on Global -> Main Settings tab -> Mark 'Suspend Frontend' as true.

This fixed my issue across all my emulator.
