works but it doesn't

[metulburr]

The script below works perfectly on my main system, the one I wrote it on. But when I transfer it to my media system, the backend fails to stay running when you close the front end.

When you say main and media systems, what are you referring to?

When you close the frontend the backend remains running.

Your going to have to get the PID when running the process to close it later.

I am assuming that both py files: one is the backend and the other is the front end?
