Problem keeping the window up

[benlyboy]

i figured it out, had to add wait...
This is the code that worked.

#!/usr/bin/python3

this is the 'starter.py' file
import subprocess
p=subprocess.Popen(["gnome-terminal","--","/home/graham/Desktop/backupwatcher/backup-client.py"])
p.wait()

Thanks to everyone that took the time to help
