Key presses rarely register when saving/loading save states

[ReyVGM]

I'm using the [11 november 2017] DEmul 0.7 WIP version, and I'm playing Atomiswave games (Metal Slug 6, Samsho6, etc.)

In Controls --> Global Hotkeys I set keyboard keys to save/load states, and to go to the next/previous state.

While playing a game, 99% of the time I have to press any of those State keys 3 or 4 times before it registers any key press. It rarely works on the first key press, most of the time I have to press it over 3 times for it to register.

Thanks for listening!
