JACK has vanished

[alectheface]

Hi, I have installed JACK, and selected the option (Minimise to system tray on lanuch) and now it has vanished, and I can't find it to use it! (is it possible my system tray is somehow hidden) Any idea's guys?
Many thanks, Alec

run qjackctl sometimes called Jack Control - should be in Multimedia menu on KDE and Sound and Video on Gnome
