I installed Skype the other day for a class I'm taking, and now my laptop isnt running right. While I work, I like to open new internet explorer windows instead of using tabs... and sometimes if I'm busy, I can get as many as 18-20 different instances of the browser running. This has never been a problem until I installed Skype. Now I get about 12 windows open and the system starts to freeze up. I can't open anything else, and can't even open links w/in the browser. If I close a window, it'll allow me to open a new window.. but eventually it locks up to the extent that I can't open or work with anything. No one else in the class has had this problem. It's almost like there's something running in the background which consumes more and more resources. Here's what I'm running: Compaq Presario C700 Vista Home -laptop is only a month or two old, and has only Norton antivirus, Office suite, and now Skype running on it.
