Spacebar E-Stop failed to work in unfocused state (AutoHotKey possibly the culprit)

I managed to get the new DS set up pretty easily—communication and gamepads were working fine, and I had a simple program running to map a gamepad axis to an ExpansionHubMotor throttle.

Things got weird when I tried testing the spacebar E-Stop feature. It wouldn't register the input at all if the Driver Station was minimized or if I was clicked into another window. After asking around, I realized I still had AutoHotkey installed from a while back, so I uninstalled that out and disabled a Lenovo hotkey service as well. It took a full restart to actually fix it, but the spacebar is finally responsive now.

I’m not 100% sure if it was AHK or the Lenovo service that caused the conflict, but AHK seems like the most likely suspect. I’ve attached a video showing how it was behaving before the restart.
