Is there a way to turn off the popping sound effect Online Armor has when blocking a connection / program? I have blocked some parts of Itunes and now when I run it I hear a popping noise every 20 seconds. It is DRIVING ME MAD. It only happens with itunes. Please, is there a way to shut that off? I really want to listen to my mp4s, but at this point I can either run Itunes or Online Armor seperately if I don't want to go screaming mad. Help!
