Just to clarify, you made sure to quit Capo first, then deleted its container, and re-launched Capo again?
When you re-launched Capo, were there no existing keyboard bindings? There should be an existing list of default bindings that include the space for play/pause, the arrow keys for movement, etc.
If you have successfully cleared the container and still see no keyboard shortcuts on launch, follow these instructions to capture some log messages for me. Specifically, I want you to quit Capo, fully delete the container directory, start logging messages, and then launch Capo to capture the startup sequence.
Hopefully we can figure out what’s going on here.
