Hi,
Touché, I wasn't aware of that. It seems the installer uses a less than optimal way of starting the process in the background, leaving you with the agent running but no way to stop it (besides using kill). Our bad, sorry about that!

Anyway, you can run the process in the foreground by simply executing loadUI-agent.sh (and using Ctrl+C to end it). I would use 'kill' first to end the currently running process(es). And if you wish to run loadUI as a daemon, I would suggest using screen or dtach as previously mentioned.
