Alright. I was wondering if anyone knows what language Instant Messenger was written in. What I'm getting at is this: I want to find the file that checks if the program is running, and if it is, then it won't open a new window , it opens the one already running. See, I want to be able to find that file, and change it so that I can open multiple windows of Instant Messenger, and be logged on as different people at the same time. I know you can go to the website and use AIM Express, but I don't want to do it that way. Could someone please help me?
