New Message Audio Alert Script
If anybody is interested, this script makes an audio alert every time a message is recieved, even if the window is in focus. It helps if you are the person that is back and forth from the computer, and would like to know if the person you are talking to has said something.
Make sure you go into the Windows Live Messenger options, then go to the Alerts and Sounds tab and disable the New Message Alert or you will here an echo when you recieve a message when a window is not in focus.
If you want to change the sound you hear when you recieve a message, go to the "C:\Program Files\Messenger Plus! Live\Scripts\New Message Alert" directory, and replace the "new_message.mp3" sound file with a different MP3 sound file. Make sure you keep the file name the same (new_message)
Special thanks to BigBob85 for helping me fix a bug in the script
