I don't use any messenger. Door was both opening and closing. Anyway my system went down due to a virus from gnutella, now I'm back on, and haven't had the sound again yet. I hope to start a new thread about that virus right now if they would ALLOW me to post a new thread. I believe the virus was a video file of TNA wrestling about Abyss vs Sabu, 1.2 KB mp4. It's still on the network. Let's hear about it. OH I don't mean this virus was causing the door.
