I can confirm this behavior as well. It's intermittent, the best type of bug... I am seeing the `window.onkeydown` event being bound to the function even after dialogs have closed......

`java -jar JTempestSDR.jar` to run the jar file. Make sure the java is in your PATH. Might be worthwhile to add a .sh for *nix and .bat files for Windows...

Looking at the forks it seems like @GwonHyeok already found [a fix](https://github.com/GwonHyeok/keystone-storage-adapter-s3/commit/9db761ae0d138d02b7b7c59fa7e59f761f5b95e8) for the issue. Looks like a better, more robust solution rather than more options.
