Describe the bug
A clear and concise description of what the bug is.
On Big Sur I tried switching my hyper-key (caps lock = shift, ctrl, option, cmd) functionality to BTT. I ran into several problems and have shelfed the attempt.
Problems I encountered:

  • non-responsive - would hit a combination a nothing would happen, would it again and action occur
  • Key would "stick" - after using hyper-key the system would "hold it down" and subsequent typing act as if the hyper-key still pressed.
  • To get keyboard back to normal I would need to restart BTT

For now, back to Karabiner-Elements for Hyper-Key
