Hi Philip,
now I red your article about this problem with tray-icon. I was very pleased that you want solve this. And I'm very happy that SW for Meamo is flexible and developing .
IMHO (if it possible) make option to stop/start DUN (?in tray menu?) and show tray icon only when BT is ON.
Sorry if is it stupid suggestion, I don't know exatly the possibilities.
