I upgraded to the newest LW Pro 4.16.2... and it's even worst than the old one 4.13. This one stopped working when I was in options changing the listening port and I could not shut it down the options panel down. So I tried to close LW in task manager. It remained open. After about 10 minutes the LW panel disappeared but is still running in the background. Now when I try to shut it down in task manager I get an access denied error... even though I'm operating as the administrator. WTF! Is it Limewire? Vista? The Java RTE?
